Snapchat Number Lookup API: Check Phone, Email & Username

Published August 24, 2026

Snapchat remains one of the largest messaging platforms among younger audiences, which makes it a valuable channel for outreach, verification, and enrichment. If your product works with phone numbers, emails, or usernames, knowing whether a contact is actually on Snapchat — and resolving the public identity behind it — can shape which channel you pick and how you score a lead. A Snapchat number lookup API answers all of this over HTTP.

This guide covers checking registration by phone, batch-checking a list, and resolving identity or a public username profile.

Step 1 — Get an API key

Sign up and copy an active key from your Dashboard. Free credits are included for testing.

Step 2 — Check a phone number

The check-phone operation takes a phone number in international format (digits, optional leading +) and returns whether it’s registered on Snapchat — plus the account’s username, userId, and displayName on a hit:

curl "https://api.opendata-api.com/api/project/snapchat/check-phone?key=YOUR_API_KEY&number=8613800138000"

registered is three-state: true = registered, false = not registered, null = undetermined (transient — retry after a short backoff).

Step 3 — Batch-check a list

For list screening, the check-phones-batch operation classifies up to 50 comma-separated numbers in a single request, returning a per-number result:

curl "https://api.opendata-api.com/api/project/snapchat/check-phones-batch?key=YOUR_API_KEY&numbers=8613800138000,8613900139000"

Fifty numbers cost one request instead of fifty — the efficient path for bulk cleaning.

Step 4 — Resolve identity or a username profile

The user-info operation looks up a phone number, email, or username and returns the public identity that surface exposes. The public-profile operation resolves a username to its display name and snapcode:

curl "https://api.opendata-api.com/api/project/snapchat/user-info?key=YOUR_API_KEY&number=8613800138000"
curl "https://api.opendata-api.com/api/project/snapchat/public-profile?key=YOUR_API_KEY&username=teng_leo"

One email caveat: an email lookup uses an account-recovery probe, so a positive hit may send a real recovery email to the owner. Use it deliberately, not for bulk spraying.

Use cases

  • Channel routing — offer Snapchat as a contact channel only where it’s actually available.
  • Lead validation — confirm numbers or emails are on Snapchat before adding them to a campaign.
  • Contact enrichment — attach a Snapchat username / userId to existing phone records.
  • Anti-fraud & KYC — use registration status as a lightweight trust signal.
  • List cleaning — batch-verify stored contacts and drop the ones that aren’t on Snapchat.

Best practices

  • Normalize numbers to E.164 (country code, digits, optional leading +) before checking.
  • Batch when you can — use check-phones-batch for lists to cut round-trips.
  • Validate before enriching — run check-phone first and only call user-info on registered contacts.
  • Handle the null state — treat registered=null as “retry later”, not as a definitive no.
  • Stay compliant — process only contacts you have a lawful basis to use, and respect privacy expectations.
