Detect iMessage-Ready Numbers
Confirm whether a phone number supports iMessage before you build an iOS-focused outreach flow.
iMessage runs on Apple's own messaging network, so a number only shows as registered when it is linked to an active Apple ID on an iPhone, iPad, or Mac. CheckNumber's iMessage checker reads that registration signal at scale — upload a CSV of numbers or call the REST API, and each row returns a registered or not-registered verdict. Teams use it to separate iPhone-reachable contacts from Android or feature-phone numbers before deciding whether an outreach flow should route through iMessage or fall back to SMS.

iMessage Checker No account, number, or SIM required
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.
What CheckNumber detects for iMessage
iMessage registration by phone
Confirms whether a number is currently registered for iMessage on an Apple device (yes or no).
iPhone-reachable segment
Every number in an iMessage batch returns a registered or not-registered result for building an iPhone-reachable segment.
Passive, no contact
Reads the registration state only — no iMessage is sent and the device owner is never notified.
What You Can Check
A focused iMessage registration check
Use the iMessage task when the required output is a row-level iMessage-enabled signal mapped to each submitted E.164 phone number.

Core iMessage data
What the iMessage task returns
The result file maps one row to each submitted number with the fields below.
Registration
imessage - Number
- The phone number supplied for the check, in E.164 format.

- Whether the number currently has iMessage enabled (yes or no).
The imessage field is a boolean signal only — it does not include profile names, photos, or other Apple ID details.

Apple ecosystem signal — confirm in bulk which phone numbers are tied to an active iMessage/Apple ID registration.

Smarter delivery routing — separate iPhone-reachable numbers from Android and feature-phone numbers before choosing SMS or iMessage.
Signal 3
Privacy-safe — a passive check that never opens Messages, sends anything, or notifies the number's owner.
iMessage FAQ
Can I check phone numbers against iMessage in bulk?
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, then download one registered or not-registered result per number. You are only billed for checks that complete successfully.
Why would a number show as not registered for iMessage?
iMessage only activates when a number is signed into an Apple ID on an iPhone, iPad, or Mac. A not-registered result usually means the number belongs to an Android or feature phone, or an iPhone with iMessage turned off — the check reports the current registration state, not the phone's brand.
Does the check contact or notify the person?
No. The check only reads the iMessage registration signal. No message is sent through iMessage or SMS, and the device owner is never notified.
Is there a free trial?
Yes. New accounts get 1,000 free checks with no credit card required, and every check afterward is pay-as-you-go with no monthly fee — top-up credit never expires.
