If you've received a call from a number starting with 519, you're hearing from someone in or around London, ON. This doesn't guarantee the caller is physically located there — phone number spoofing allows any caller to display a local area code. A reverse phone lookup can tell you the actual registered carrier and owner behind the number, regardless of what your caller ID shows.

The 519 area code has been active since 1953 and is managed by NANPA (North American Numbering Plan Administration) under the North American Numbering Plan. Numbers in this area code follow the standard NANP format: (519) XXX-XXXX.

How to Look Up a 519 Phone Number

Looking up a 519 number on RevealNames is straightforward. Enter the full 10-digit number (including the 519 area code) into the search box at the top of this page. Our system cross-references carrier CNAM databases, public records, and spam report databases to return:

  • The registered owner's full name — first and last name as registered with the carrier
  • City and state location — where the number is registered, which may differ from the caller's physical location
  • Carrier name — AT&T, Verizon, T-Mobile, or any of the regional or MVNO carriers serving the London area
  • Line type — whether the number is a mobile cell phone, landline, VOIP line, or toll-free number
  • Spam reports — community-sourced flags if the number has been reported for robocalling, telemarketing, or fraud

Results are returned anonymously — the person you're looking up never finds out you searched their number.

Phone Scams Targeting 519 Numbers

Like every active area code, 519 numbers are regularly spoofed by scam operations. When a call comes from what looks like a local London, ON number but turns out to be a robocall or fraud attempt, the scammer is using neighbor spoofing — a technique that replaces the real originating number with a local-looking one to boost answer rates.

Common scams hitting 519 numbers include IRS impersonation calls, fake Social Security Administration notices, auto warranty robocalls, Medicare fraud attempts, and "local business survey" calls that are actually lead harvesting operations. The 519 area code is particularly targeted because of the population density and income demographics of the London area.

Before you call back a 519 number you don't recognize, run a free reverse phone lookup above. A genuine call from a business or individual will have a registered name and carrier. A spoofed scam number often shows as unregistered, assigned to a VOIP carrier, or has multiple spam reports attached to it.

If you identify a scam number, report it to the FTC at reportfraud.ftc.gov and the FCC at consumercomplaints.fcc.gov. Your reports help build enforcement cases.
