Suspected Robocall · Risk 55/100What callers from (640) 800-2521 say
Caller pretending to conduct a Census follow-up survey asked for my full SSN and bank account number.
Why this matters: calls from this number have appeared in our directory 9 times across 3 distinct user reports between 2025-01-28 and 2025-06-08. Multiple independent reports describing the same script are a strong signal that the number is being used by an organized scam operation rather than a one-off mistake or wrong-number call.
The script associated with this number falls under our Census / Federal Survey category, where the caller pretends to represent the U.S. Census Bureau. Read the category page for the broader pattern this fits into and how to verify whether you are actually being contacted by the agency in question.
Where the number is calling from
The caller-ID number reported is (640) 800-2521, with the area code 640 historically assigned to PA. That does not mean the call physically originates there. Modern voice-over-IP services let scammers display essentially any number on the recipient's caller-ID screen, and the most common pattern is to spoof a number with the same area code as the person being called so the call looks "local." If you've received a call you believe came from this number, do not rely on the displayed caller-ID as evidence of who actually called you.
If this number is yours
It is genuinely possible that the number on this page is a real, legitimately-owned phone line whose caller ID has been spoofed by a scam operation without the owner ever placing a call. If that's the case for you, see our contact page for the process to add a clarifying notice or have the listing removed.
Reader Reports
Pitched a federal government job that required a $99 background check fee paid up front. Federal jobs are posted at usajobs.gov and never charge applicants.
Said he was conducting a "post-Census follow-up." Wanted my SSN and "household income from all sources." Real Census surveys don't ask for SSN.
Asked who I was voting for and then asked for a credit card to make a "small contribution" to support the Census Bureau. Census Bureau does not solicit donations.

What you should do if this number called you
- Don't call back. The number may auto-route to an overseas call center. Returning the call confirms a working line.
- Block the number. Most modern phones have built-in spam blocking; block the full number, not just the prefix.
- Report it to the impersonated agency. File a complaint with the FTC at reportfraud.ftc.gov and, if the call impersonated U.S. Census Bureau, with that agency directly through its official complaint channel.
- Tell us. Adding your report helps the next person who searches this number find the warning sooner.
