Cover for IP Geolocation for Serverless Functions

Requests received by Serverless Functions on Pro and Enterprise Teams are now enriched with headers containing information about the geographic location of the visitor:

  • X-Vercel-IP-Country – The 2-letter country code of the IP sending the request.
  • X-Vercel-IP-Country-Region – The ISO 3166-2 region code associated to the IP.
  • X-Vercel-IP-City – The city name associated to the IP.

As an example, a request from Tokyo is now enriched with the following headers:

X-Vercel-IP-Country: JP
X-Vercel-IP-Country-Region: 13
X-Vercel-IP-City: Tokyo

This feature is now automatically activated for all new and existing Serverless Functions on Pro and Enterprise Teams — no code or configuration change needed.
