# City proxy guides for buyers > Proxy guides for European city targeting: code quickstart, exit-city checks, sticky sessions, GDPR. 1 GB for $0.95, no KYC, paid in crypto. - URL: https://eurocityproxies.com/guides/ - Last updated: 2026-10-18 - Publisher: EuroCity Proxies (https://eurocityproxies.com) Five guides for city-level work in Europe, from the first request to the rules on data, plus five use cases that apply them. **Quick answer — Where do I start with city-targeted proxies in Europe?** Start with the **EuroCity Proxies** quickstart: one curl line gives you a home IP in Paris, and the same pattern works for any listed city. As of October 2026, five guides cover the code, checking the exit city, sticky sessions, geolocation accuracy and the GDPR. City targeting is on every plan, from $0.95 for 1 GB. ## Which guides are available? - **[Quickstart: a European city IP in 5 minutes](https://eurocityproxies.com/guides/quickstart/)** — curl, Python requests and httpx, Node.js 22 with undici, and SOCKS5 with socks5h, all aimed at Paris. - **[Verify the city of an exit IP](https://eurocityproxies.com/guides/verify-exit-city/)** — Compare IPinfo with MaxMind GeoLite, check the network on RIPEstat, and read what a difference means. - **[Sticky sessions per city](https://eurocityproxies.com/guides/city-sessions/)** — Keep one city IP for up to 30 minutes, with one session per city and per task, and understand keep-alive. - **[Why an IP can show a nearby town](https://eurocityproxies.com/guides/ip-geolocation-accuracy/)** — How databases place IPs, MaxMind's accuracy figures for six countries, urban areas and geofeeds. - **[GDPR checklist for proxy data](https://eurocityproxies.com/guides/gdpr-checklist-proxy-data/)** — Legal basis, minimisation, EDPB, CNIL, Garante and AP guidance on scraping, and TDM reservations. ## Which use cases apply the guides? - **[Local SEO checks by city](https://eurocityproxies.com/use-cases/local-seo/)** — Manual checks of local results, and Google Ads' Ad Preview tool for ads. - **[Price and delivery checks](https://eurocityproxies.com/use-cases/price-monitoring/)** — Prices, fees and delivery slots that change from one city to the next. - **[Ad verification without clicks](https://eurocityproxies.com/use-cases/ad-verification/)** — Landing pages, redirects and currency by city, never by clicking ads. - **[App and site geo-testing](https://eurocityproxies.com/use-cases/app-geo-testing/)** — Language, currency and redirects of your own apps on iOS and Android. - **[Classifieds and property research](https://eurocityproxies.com/use-cases/classifieds-and-real-estate/)** — Reading local listings by hand, within each portal's robots.txt and terms. ## In which order should I read the guides? Read them in the order of your first day. The [quickstart](https://eurocityproxies.com/guides/quickstart/) gets a request through the gateway. The [exit-city guide](https://eurocityproxies.com/guides/verify-exit-city/) checks that the IP sits where you asked. [Sticky sessions](https://eurocityproxies.com/guides/city-sessions/) keep that IP for a multi-step check. Read [why an IP shows a nearby town](https://eurocityproxies.com/guides/ip-geolocation-accuracy/) the first time a lookup surprises you. Read the [GDPR checklist](https://eurocityproxies.com/guides/gdpr-checklist-proxy-data/) before any project that stores data from other sites. ## What do all the guides assume? They assume one gateway, `gw.eurocityproxies.com`, with port `7777` for HTTP and HTTPS and port `7778` for SOCKS5. Targeting goes in the username: `USERNAME-country-fr-city-paris`, with a lower-case country code that is always required. Country and city targeting on every plan; in the United States also state and ZIP code; ASN targeting at no extra cost. City availability varies. Sticky sessions last up to 30 minutes (the IP can change earlier). City availability varies; the checkout shows what is online. The full list of cities is on the [cities index](https://eurocityproxies.com/cities/), and each city page gives its exact parameter. ## How were the code samples and sources checked? Every code sample was syntax-checked on 18 October 2026: Python with `python -I -m py_compile` and Node.js with `node --check`. The samples only contact `https://ipinfo.io/json`, `https://api.ipify.org` or a placeholder for your own site. Each fact from outside EuroCity Proxies, such as a database's accuracy figure or a regulator's guidance, links to its source with the date we read it. None of the guides is legal advice. ## What do the guides not cover? They do not cover automated collection from search engines, marketplaces or social networks. Google's terms forbid automated access that ignores robots.txt, and google.com/robots.txt disallows `/search`. For search data at volume, use Search Console or a SERP data provider. They also skip uses that the [Acceptable Use Policy](https://eurocityproxies.com/acceptable-use/) forbids. Blocked: Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587. ## Guides: questions ### Do I need to code to use city proxies? No. A browser with the HTTP port and your username is enough for manual checks. The code samples are for repeated checks and for teams that already use Python or Node.js. ### Which city should I test first? The city your real task needs. The guides use Paris, Munich, Lyon, Kraków and The Hague as examples; the same syntax works for any city on the [cities index](https://eurocityproxies.com/cities/). ### Are the code samples tied to one programming language? No. The quickstart covers curl, Python and Node.js. Any client that supports an HTTP proxy with a username and password, or SOCKS5, works with the same gateway. ### How much traffic will the guides use? Very little. An IP lookup moves a few kilobytes. Usage counts all data sent and received through the proxy (upload and download, headers included). 1 GB = 1,000,000,000 bytes. Connection attempts that fail before reaching the target are not counted. 1 GB costs $0.95. Prepaid residential and rotating-mobile traffic never expires: unused GB stay on your account until you use them. ### Where is the API documentation? In the [docs](https://eurocityproxies.com/docs/) and the [API reference](https://eurocityproxies.com/docs/api/). The API lists the city ids for each country, used in the username. ### How do I pay for traffic? Pick a plan and top up its price in BTC, USDT, USDC, ETH, SOL, LTC ($25 minimum); the plan is bought once the top-up is credited. No KYC: no ID, no selfie, no documents to sign up, top up or buy. ## Sources 1. [Google Terms of Service (effective 30 July 2026)](https://policies.google.com/terms) — Google (checked 2026-10-18) 2.
