Know which numbers are alive before you send.
Upload a list or call the API. Landlines, litigators and do-not-call numbers come out the way you choose, and you pay in credits for only what you run.
- (415) 555-0142reachable
- (212) 555-0188landline, removed
- (801) 555-0119litigator, removed
- (303) 555-0167reachable
Dead numbers cost the same to text as live ones.
Carriers bill you for the send, not the delivery. Every landline, deactivated line and flagged number in your list is money out the door, and every one that bounces teaches carriers to trust your traffic less. Clean the list first.

Know more than “reachable.”
Add the details your team actually uses, and leave the rest.
- carrier name and ID
- line type: mobile, landline, VoIP
- ported numbers, with the new carrier and port date
- time zone and location
- how long the number has been active
- whether a texted link was ever clicked
Dashboard or API. Same engine.
Dashboard
Check one number or a million. Import a list, pick your options, watch it run, download the result. Every number lands in your account with its latest result, so you can search, filter and export it later.
Download the kept numbers and the removed ones, each with its reason.
API
One call in, one answer out. Send a number, get back the options you asked for. Use it at the form, in the dialer, in your CRM. Every API lookup also lands in your dashboard, so nothing lives only in a log.
curl https://numberalive.com/api/v1/lookup \
-H "Authorization: Bearer YOUR_API_KEY" \
-d phone=4155550142 -d remove_landline=1 \

"phone": "4155550142", "keep": true, "reasons": [],

Prepaid credits. No subscription.
Buy credits, run lists, see the cost before every run. Options show their credit cost up front, so there are no surprises on the invoice.

- $60200,000 credits
- $120400,000 credits
- $3001,000,000 credits
One flat price on every order: $0.0003 per credit, so carrier and line type cost $0.30 per 1,000 numbers and $300 per million.

FAQ
Does NumberAlive verify international numbers?
US and Canada only, for now.
How do credits work?
One lookup spends credits based on the options you chose. The cost shows before you run a list.
Is there a free trial?
Not a trial, but we will clean a 1,000-number sample of your list free: claim your sample. After that, the smallest purchase is $20.
Do you keep my lists?
Yes, in your account, until you delete them.
How do I use the API?
Create a key in your dashboard and see the API docs.
Make sure the next send lands.
