Anchor Browser geo routing uses lowercase country_code - each session gets its own residential IP

TL;DR

Set idletimeout low (30s) on geo jobs since each region holds its own session, and stop sessions in a finally block or you stack up billing. For geo-targeted scraping on Anchor Browser, pass the country as a lowercase ISO code: anchor.sessions.create(proxy={'active': True, 'countrycode': 'de'}, ...).

Fix

1. Set idle_timeout low (30s) on geo jobs since each region holds its own session, and stop sessions in a finally block or you stack up billing. Expected: You get the expected result; the problem is gone.

When to use

• You are dealing with this situation.
• The symptom matches: Anchor Browser geo routing uses lowercase country_code - each session gets its own residential IP.

When NOT to use

• Unrelated issues with a different cause.
• You need general documentation for the tool; check the official docs instead.

Anchor Browser geo routing uses lowercase country_code - each session gets its own residential IP

Why it happens

Official Anchor Browser blog (Geo-Targeted Price Monitoring): set countrycode to any ISO 3166-1 alpha-2 code and Anchor routes the session through a residential IP in that country - the worked example uses lowercase codes (REGIONS = ['us', 'de', 'au', 'gb', 'sg']) passed as proxy={'active': True, 'countrycode': country_code}. Each parallel session gets its own isolated context, IP, and fingerprint via asyncio.gather, so geo comparison jobs look like separate visitors.

Resolved: For geo-targeted scraping on Anchor Browser, pass the country as a lowercase ISO code: anchor.sessions.create(proxy={'active': True, 'countrycode': 'de'}, ...). The official example uses lowercase codes (us, de, au, gb, sg) - do not send uppercase. Each session gets its own residential IP and fingerprint, so firing parallel sessions across regions with asyncio.gather gives you per-region snapshots that look like separate visitors.
