Every check runs through official platform APIs on our own infrastructure. You never connect, bind, or use your own account, phone number, or SIM card — just upload your list or call the API and get results.
CheckNumber's MAX checker tells you whether a phone number is registered on MAX messenger and, for registered numbers, returns a full profile, without messaging or storing the number. Upload a CSV of numbers or call the REST API, and every row comes back with a clear registration verdict plus the profile signals below, ready to clean lists, enrich records, or route into your CRM.

MAX FAQ
Can I check phone numbers against MAX in bulk?
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, choose the task type you need, then download a result file with a registration verdict for every number. You are billed only for successful checks.
What profile details can the MAX checker return?
For registered numbers, the full task type returns the account id, display name, gender, a last-seen activity description, and an avatar URL where available. Numbers that are not registered have empty profile fields.
Does a MAX check message or notify the person?
No. The check is passive and reads registration and profile signals only. Nothing is sent to the number, and the account owner is never contacted or notified.
Is there a free trial?
Yes. New accounts receive 1,000 free checks on signup with no credit card, and every check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
