How to tell a text is really from us
Scammers sometimes send texts that use the names of real companies. A text that mentions Snap Diagnostics is not always from us, so it is worth taking a moment to check.
- Check the sender. Our patient texts come only from (847) 957-1156. A text that uses our name but comes from any other number is not from Snap Diagnostics.
- Only call the numbers on this page. To reach us, call (847) 777-0000 or (217) 457-3065, even if a text lists a different number.
- When in doubt, contact us yourself. Do not reply to the text or tap its links. Call us, or type snapdiagnostics.com into your browser.
- Report suspicious texts. Forward them to 7726 (SPAM), then delete them.
If your text came from (847) 957-1156 and asks you to call one of the numbers above, it is from us, and you can register with confidence.
