Calling USPTO Trademarks from outside the US
The Trademark Assistance Center lists an international number, 1-571-272-9250 (press 0), alongside its toll-free 1-800-786-9199 (press 1). It's open Monday to Friday 9am to 4pm Eastern and closed on federal holidays. It's the USPTO's main support centre for trademark filers, but it can't give legal advice, such as how to respond to an office action or which class to file in. You can also email TrademarkAssistanceCenter@uspto.gov.
Common reasons people call from abroad:
- General questions about the US trademark application process
- Problems with the USPTO's online trademark forms
- Brand owners abroad preparing a US trademark for a marketplace brand program

Why +1 800-786-9199 fails from a foreign phone
On a toll-free number, USPTO Trademarks pays for the call instead of you. Carriers generally only route these calls from networks inside the area the number covers, here the US. A call from a foreign SIM, or from a home SIM roaming on a foreign network, has nobody to bill it to, so the network rejects it. You usually hear "your call cannot be completed as dialled", a fast busy tone or silence.
VoixCall places your call from inside the US network, so to USPTO Trademarks it looks like a US caller and the toll-free line connects. You can call it from the VoixCall app or a browser in any country, or dial +1 571-272-9250 instead.

How Much Does It Cost?

Your first call is free. After that you pay from prepaid credit, with no subscription. Recording adds $0.003/min. Rates as of 2026-10-06; see current rates for the US.
Record the call and keep the reference number
A call to USPTO Trademarks usually ends with a case or reference number and a promise about what happens next. After a long hold, in a second language, it's easy to miss a digit.
Switch on Record on the VoixCall dialer before you call ($0.003/min). If you've also turned on "Record and transcribe my calls" in Settings (web or the iPhone/Android app), about a minute after you hang up Call History shows a short summary, the reference numbers that were said (each with a Copy button), what each side agreed to do next, and the full transcript, for $0.02/min.
Recording is off by default. USPTO Trademarks hears a short recording notice when the call connects, and only you can see your recordings and transcripts. Speech-to-text can mis-hear fast numbers, so check important digits against the recording. Recording laws differ by country. How call transcripts work →
