What we don't offer
- Reverse lookup: We never return the name, photo, profile, username or social account behind a phone number or e-mail address.
- Demographics: No age, gender, ethnicity, appearance, income or other inference about the person.
- Adult-site checks: We do not check whether a number or address has an account on adult sites.
- Location and SIM data: No subscriber location, cell or device identifiers, and no SIM-swap check. Sensitive network identifiers are never returned.
- Self-serve spam reputation: Spam reputation is limited access: approved customers only, for numbers from all countries except sanctioned ones.
- Sanctioned countries: Numbers from sanctioned countries and regions are never checked and never billed: every check answers unsupported_country.
- E-mail checks for every domain: E-mail checks cover major webmail providers only. Company and custom domains return unknown (UNSUPPORTED_PROVIDER) and are not charged; we never send mail or connect to the mailbox.

Frequently asked questions
What is MobileValidate?
A phone-number and e-mail intelligence API. One request checks whether a number or address is registered on messaging apps and online services, and returns carrier, line type, live network status (HLR), number portability (MNP) and (for approved customers) spam reputation. Every answer is registered, not registered or unknown, with a checked_at time.
Who operates MobileValidate?
The MobileValidate team. The legal entity you contract with is named in the Terms of Service (https://mobilevalidate.com/legal/terms). Support: support@mobilevalidate.com; sales: sales@mobilevalidate.com.
Is MobileValidate affiliated with WhatsApp, Telegram or the other platforms it checks?
No. It is an independent service, not affiliated with, endorsed or sponsored by those platforms. Their names are used only to describe what a check covers.
Does a check send a message to the number or e-mail address?
No. A check never sends a message, call or e-mail and never opens a mailbox. The person behind the number or address is not contacted.
Can it tell me who owns a phone number?
No. We don't do reverse lookups: checks never return names, photos, profiles or locations.
What am I charged for?
Only conclusive answers. You're not charged for inconclusive results (unknown, unsupported country, timeout, invalid, duplicate). Cache hits and test keys are free.
Can I try it without signing up?
Yes. The public sandbox key in the docs answers the documented test numbers and addresses and is never billed. See https://mobilevalidate.com/docs/test-values.
Is there an MCP server for AI agents?
Yes: https://mcp.mobilevalidate.com/mcp (streamable HTTP) or npx -y @mobilevalidate/mcp. It takes scoped, spend-capped agent keys or test keys; live keys are rejected.
Do you offer HLR and MNP lookups?
Yes. The HLR lookup (number.hlr) asks the mobile network live whether a number is reachable, ported or roaming. The MNP lookup (number.mnp) answers only whether the number was ported and its current network code, at a lower price. Unknown answers are free.
How long do you keep the numbers I check?
Realtime lookups for 7 days; bulk jobs for 30 days by default (1 day to 24 months per account). You can delete a finished job at any time, and logs hold masked identifiers only.
