Better Auth doesn't add the user's country to the session by default, but you have a few ways to include it:

  1. If your OAuth provider returns country info, you can add custom fields like country to your user object using the additionalFields config and map it in mapProfileToUser. Then, use the customSession plugin to expose it in the session response (example):
// In your auth config
additionalFields: {
  country: { type: "string" },
  countryCode: { type: "string" }
},
mapProfileToUser: async (profile) => ({
  // ...other fields
  country: profile.data.personal.country.name,
  countryCode: profile.data.personal.country.id,
})

// In your custom session plugin
import { customSession } from "better-auth/plugins/custom-session";
export const myCustomSession = customSession(async ({ user, session }, ctx) => ({
  ...session,
  country: user.country,
}));
  1. If you want to derive country from the user's IP, use a geolocation package like geoip-lite in your custom session function (example):
import geoIp from "geoip-lite";
customSession(async ({ user, session }) => {
  let country = undefined;
  if (session.ipAddress) {
    const res = geoIp.lookup(session.ipAddress);
    if (res) country = res.country;
  }
  return { ...session, country };
});
  1. If you're running on Cloudflare, the cloudflare plugin can automatically add geolocation fields (including country) to the session (details).

For all approaches, be mindful of privacy and only enrich sessions with location data if users have consented. If you want to persist country info in your database, use a database hook to update the user or session record on sign-in (feature discussion).

You can add additionalFields to the user schema.
