1. Assumptions Behind the Numbers
Phone validation pricing pages are designed to show the lowest per-lookup figure a vendor can honestly print. That number is real, but it usually assumes you buy the largest tier and use every request in it. This post does the math the other way around: start with a volume, then work out what each vendor actually charges for it.
We have already covered how per-lookup pricing works in carrier lookup pricing explained, and the trade-offs between models in pay-as-you-go vs subscription pricing. We will not repeat that here. This is the vendor-by-vendor cost sheet.
Rules used throughout:
- List prices only, as published in mid-2026. No negotiated or enterprise discounts.
- Smallest plan or pack that covers the volume, unless a bigger plan is cheaper (for example, when overage costs more than upgrading).
- Monthly billing for subscriptions. Annual billing discounts are noted separately.
- Carrier plus line type is the job being priced. Where a vendor charges extra for current (portability-aware) carrier data, we price that.
- PilotLookup: Starter 5,000 for $25, Professional 25,000 for $75, Business 125,000 for $125, Enterprise 500,000 for $300. Credits never expire.
Every figure here comes from published list pricing as of mid-2026. Vendors adjust prices and tiers regularly. Verify current pricing on each vendor's site, and ask for a quote at high volume, before you commit budget.
2. Published Phone Validation Pricing at a Glance
| Vendor | Coverage | Model | Published price points |
|---|---|---|---|
| PilotLookup | US only | Non-expiring credit packs | $0.005 → $0.003 → $0.001 → $0.0006 per lookup |
| Numverify | 232 countries | Monthly subscription | $14.99/5,000; $59.99/50,000; $129.99/250,000; overage per request |
| Twilio Lookup (Line Type Intelligence) | Global | Per request, per package | $0.008 per request; other packages billed separately |
| Telnyx Number Lookup | See vendor docs | Per request | ~$0.0015, volume down to ~$0.001 |
| Plivo Lookup | See vendor docs | Pay-as-you-go | ~$0.004 per request |
| Veriphone | 240+ countries | Credits | ~$0.0002 per credit at the largest pack; current carrier = 10 credits |
| Abstract API | 195+ countries | Monthly subscription | From $19/month, scales with volume |
| Telesign Phone ID | Global | Per transaction | ~$0.011 per transaction |
| Trestle | See vendor docs | Per lookup | ~$0.015 per lookup |
IPQualityScore does not publish pricing, and Abstract API's tier volumes vary, so neither is modeled in the cost tables below. Ask both for a quote at your volume.
3. Monthly Phone Validation Pricing at 10K, 50K, 125K and 500K Lookups
This is the cost of a single month at each volume. For PilotLookup, the cost is the cheapest pack purchase that covers that month; leftover credits roll forward.
| Vendor | 10,000 / mo | 50,000 / mo | 125,000 / mo | 500,000 / mo |
|---|---|---|---|---|
| PilotLookup | $50 (2 × Starter) | $125 (Business, 75k carry over) | $125 (Business) | $300 (Enterprise) |
| Numverify | $59.99 (Professional) | $59.99 (Professional) | $129.99 (Enterprise) | $654.99 (Enterprise + 250k overage) |
| Telnyx (~$0.0015) | $15 | $75 | $187.50 | $750 ($500 at ~$0.001) |
| Veriphone, current carrier (floor)* | $20 | $100 | $250 | $1,000 |
| Plivo (~$0.004) | $40 | $200 | $500 | $2,000 |
| Twilio LTI ($0.008) | $80 | $400 | $1,000 | $4,000 |
| Telesign (~$0.011) | $110 | $550 | $1,375 | $5,500 |
| Trestle (~$0.015) | $150 | $750 | $1,875 | $7,500 |
*Veriphone floor = 10 credits × ~$0.0002 = ~$0.002 per live current-carrier lookup, at the largest pack's rate. Smaller packs cost more per credit, and Veriphone's 1,000 free monthly credits would cover about 100 current-carrier lookups. Standard (non-live) Veriphone lookups are about one-tenth of these figures.
Showing the Numverify math
- 10,000/month: Basic ($14.99 for 5,000) plus 5,000 overage at ~$0.012 = $74.99. Professional at $59.99 is cheaper, so we use it, with 40,000 requests unused.
- 125,000/month: Professional plus 75,000 overage at ~$0.0048 = $419.99. Enterprise at $129.99 is far cheaper, with 125,000 requests unused.
- 500,000/month: Enterprise ($129.99 for 250,000) plus 250,000 overage at ~$0.0021 = $654.99. At this volume a custom plan from APILayer is likely available; ask for one.
At 10,000 a month, Telnyx and Plivo are cheaper than PilotLookup on a single-month basis. From 125,000 a month, PilotLookup's Business and Enterprise packs are the lowest list price in the table for current carrier and line type.
4. One-Time 100,000-Number List Clean
A one-off CRM cleanup or a purchased-list check is where pricing models diverge the most. Subscriptions are built for recurring use; a single job exposes the waste.
| Vendor | How you would buy it | Cost | Leftover or waste |
|---|---|---|---|
| PilotLookup | 1 × Business pack | $125 | 25,000 credits kept, never expire |
| Numverify | 1 month of Enterprise, then cancel | $129.99 | 150,000 requests lost at month end |
| Numverify (alt.) | Professional + 50,000 overage at ~$0.0048 | $299.99 | None |
| Telnyx | 100,000 × ~$0.0015 | $150 ($100 at ~$0.001) | None |
| Veriphone, current carrier (floor) | 1,000,000 credits × ~$0.0002 | $200 | Credits don't expire |
| Plivo | 100,000 × ~$0.004 | $400 | None |
| Twilio LTI | 100,000 × $0.008 | $800 | None |
| Telesign | 100,000 × ~$0.011 | $1,100 | None |
| Trestle | 100,000 × ~$0.015 | $1,500 | None |
Budget time as well as money. PilotLookup's rate limit on a Business pack is 200 requests per minute, so 100,000 lookups take about 8.3 hours of continuous scripted calls; on an Enterprise pack (500 req/min) it is about 3.3 hours. PilotLookup has no CSV upload, so bulk jobs run as concurrent API calls from your own script. Our guide to bulk phone number validation includes a ready-made script.
Run the list through libphonenumber and remove duplicates before paying for lookups. On typical CRM exports, that alone can remove a meaningful share of rows, and every vendor in the table charges per request.
5. Annual Cost Comparison
Over a year, the pricing model matters as much as the rate. PilotLookup is priced as the cheapest pack mix for 12 months of volume, bought up front (credits never expire). Subscriptions are 12 × the monthly figure above; Numverify's annual billing would cut its figures by roughly 15–20%.
| Vendor | 120K / yr (10K/mo) | 600K / yr (50K/mo) | 1.5M / yr (125K/mo) | 6M / yr (500K/mo) |
|---|---|---|---|---|
| PilotLookup | $125 (1 × Business) | $425 (Enterprise + Business) | $900 (3 × Enterprise) | $3,600 (12 × Enterprise) |
| Numverify (monthly billing) | $719.88 | $719.88 | $1,559.88 | $7,859.88 |
| Telnyx (~$0.0015) | $180 | $900 | $2,250 | $9,000 ($6,000 at ~$0.001) |
| Veriphone, current carrier (floor) | $240 | $1,200 | $3,000 | $12,000 |
| Plivo (~$0.004) | $480 | $2,400 | $6,000 | $24,000 |
| Twilio LTI ($0.008) | $960 | $4,800 | $12,000 | $48,000 |
| Telesign (~$0.011) | $1,320 | $6,600 | $16,500 | $66,000 |
| Trestle (~$0.015) | $1,800 | $9,000 | $22,500 | $90,000 |
Effective per-lookup cost for the two lowest-priced options: PilotLookup works out to about $0.00104, $0.00071, $0.0006, and $0.0006 across the four columns; Numverify to about $0.0060, $0.0012, $0.00104, and $0.00131. Numverify's 10,000-per-month figure is high because the cheapest covering plan (Professional) leaves 40,000 requests unused every month.
6. Hidden Costs in Phone Validation Pricing
The rate card is only half the bill. These are the factors that change what you actually pay, and they explain most of the differences in the tables above.
| Vendor | Quota resets | Overage rate | Credit expiry | Per-package add-ons | Credit multipliers |
|---|---|---|---|---|---|
| PilotLookup | No quota | None; buy another pack | Never expire | None; one call returns all fields | None (1 credit per lookup) |
| Numverify | Monthly | Basic ~$0.012, Professional ~$0.0048, Enterprise ~$0.0021 | Unused quota lost each month | None | None |
| Twilio Lookup | No quota | N/A (per request) | N/A | Line type, line status, caller name, SIM swap, identity match, reassigned number each billed separately | N/A |
| Veriphone | Free credits monthly | N/A (credits) | PAYG credits don't expire | None | Live current carrier = 10 credits |
| Abstract API | Monthly | Check plan | Monthly quota | Risk data on higher tiers | Check docs |
| Telnyx / Plivo | No quota | N/A (per request) | N/A | Check docs | Check docs |
| Telesign | Check contract | Check contract | Check contract | Subscriber name/address add-ons | Check docs |
Quota resets punish uneven usage
A monthly plan sized for your busiest month is oversized for every other month. If your usage swings 2× or more, quota waste can cost more than the difference in per-lookup rates.
Add-ons multiply quickly
Twilio lookup pricing is per package. If your fraud logic calls Line Type Intelligence and one other $0.008-class package on every number, you have effectively doubled your rate. Decide which signals you truly need on every request and which only on a risky subset; our carrier lookup API best practices cover caching and tiered checks that keep request counts down.
Credit multipliers hide the real rate
Veriphone's ~$0.0002 headline is for standard lookups. A live current-carrier lookup uses 10 credits, so the comparable rate for portability-aware carrier data is about $0.002. For teams that need accurate carriers on ported numbers, that is the number to compare.
7. Who Wins Where (the Honest Version)
Here is the summary without spin:
- Steady, fully used volume favors Numverify. At full monthly utilization, Numverify Enterprise is about $0.00052 per lookup, cheaper than every PilotLookup pack, including Starter ($0.005), Professional ($0.003), and even Enterprise ($0.0006). Numverify Professional at full use (~$0.0012) also beats PilotLookup's Starter and Professional packs. If you consume 250,000 lookups every month like clockwork, Numverify Enterprise on annual billing is hard to beat on price.
- Low monthly volume favors Telnyx or Plivo on a single-month basis, as long as you don't need what they don't return.
- PilotLookup wins on non-expiring credits. Spiky usage, one-off list cleans, and anything below a plan's full quota cost less when unused credits carry forward instead of resetting.
- PilotLookup's Business and Enterprise packs win at volume for US carrier and line type: $0.001 and $0.0006 per lookup, with no add-ons and no multipliers.
- Twilio, Telesign, and Trestle cost more because they sell more. If you use SIM swap, identity, or activity signals, compare them to each other, not to a carrier lookup.
Remember that PilotLookup covers US numbers only. If your traffic is international, the US-only figures above do not apply to you.

Most vendors offer a free allowance for evaluation. PilotLookup gives 10 free lookups at signup with no card. See free phone validation API tiers compared for the full list.
8. FAQ
How much does phone validation cost per lookup?
Published list prices for carrier and line type lookups range from about $0.0002 (Veriphone standard lookups at the largest pack) to about $0.015 (Trestle). For portability-aware US carrier and line type data, most teams land between $0.0006 and $0.008 per lookup depending on vendor and volume.
Is Numverify pricing cheaper than PilotLookup?
At full, steady monthly use, yes: Numverify Enterprise is about $0.00052 per lookup versus $0.0006 for PilotLookup Enterprise. When usage is uneven or below the plan's quota, PilotLookup's non-expiring credits are usually cheaper over a year.
What does Twilio Lookup pricing look like at 100,000 lookups?
Line Type Intelligence at the $0.008 list price is $800 for 100,000 requests. Other packages are billed separately. Negotiated volume pricing can be lower; ask Twilio.
Do PilotLookup credits expire?
No. Credits never expire, and your rate limit is set by the largest pack you have bought: 30, 100, 200, or 500 requests per minute.
What is the cheapest way to clean a one-time list?
Choose a model with no monthly reset. At 100,000 US numbers, a PilotLookup Business pack ($125) or Telnyx per-request pricing (~$100–$150) are the lowest list options in our comparison.
9. Conclusion
Phone validation pricing only makes sense at your volume and your usage pattern. Steady, fully used global traffic favors a subscription like Numverify. Small, steady US volume can be cheapest on per-request vendors like Telnyx. Uneven usage, one-off list cleans, and US volume from 125,000 lookups a month upward favor non-expiring credit packs like PilotLookup's. Plug your own monthly numbers into the tables above, account for the hidden costs, and verify every vendor's current prices before you sign. When you are ready, compare packs on our pricing page.
