Mercury Mobile App Tips for International Travel

Mercury's risk model flags accounts that show frequent IP changes across countries. For non-resident founders traveling internationally, this can trigger account reviews. Here are the mobile app tips to minimize flags while maintaining account access.

Answer

Mercury mobile app tips: (1) Use a single phone number on file across all logins. (2) Enable Mercury 2FA with authenticator app (not SMS, which can fail abroad). (3) Notify Mercury before major travel (international roaming notice). (4) Avoid VPNs from rapidly changing locations. (5) Keep your registered passport/ID up to date in Mercury verification. Following these reduces account flag risk significantly.

Tip 1: Single phone number across logins

Mercury logs your phone numbers used during 2FA. Changing phone numbers (because you switch SIM cards while traveling) triggers reviews. Use a Wise card-tied phone or eSIM that maintains the same number across countries.

Tip 2: Use authenticator app for 2FA

SMS-based 2FA fails when traveling (no roaming, expensive). Authenticator apps (Google Authenticator, Authy) work offline globally. Set up before traveling.

Tip 3: Pre-notify Mercury for travel

Email Mercury support ahead of major international travel windows. "I will be traveling from US to India for 2 months starting Oct 1." They flag your account as expected to log in from India. Reduces flag risk.

Tip 4: VPN considerations

Static VPN to one country (consistent location) does not flag. Rotating VPN across rapid country changes flags. Either use a stable VPN exit point or no VPN at all.

Tip 5: Keep ID current

Your passport must remain valid (12+ months remaining). If your passport expires while traveling, Mercury may flag during routine identity refresh. Renew before travel if expiration is approaching.

What to do if your account gets flagged

Stay calm. Mercury support resolves most flags within 2-5 business days. Submit requested ID and travel details. Avoid panicking and creating multiple support tickets. Single thread with clear context resolves fastest.

Frequently asked questions

Does Mercury require US-based phone number?

Not required at signup. But your registered phone number should be consistent for 2FA reliability.

What if I lose my phone abroad?

Contact Mercury support immediately with recovery codes (backup codes you saved at 2FA setup). Mercury resets 2FA after verification.

Will Wise have the same travel issues?

No. Wise is built for international users. Travel does not flag Wise accounts.

Can I freeze and unfreeze cards from the app?

Yes via Mercury mobile app. Useful when traveling to flag suspicious card usage immediately.
