ISP IPs from $3.80/month · Residential from $0.80/GB · Mobile sticky up to 24 h
Proxies for multi-account management give each account you run its own IP address in the right country, so two storefronts, two client ad accounts or two regional profiles never share a connection. Quantum Proxies offers dedicated ISP IPs from $3.80 per month, residential sticky sessions from $0.80/GB and mobile carrier IPs from $2.30/GB, all assigned per account from the dashboard or API.
Marketplaces, ad platforms and social networks record the IP address behind every login and tie it to the account. When an agency signs into ten client accounts from one office connection, the platform sees ten accounts on one address, and a review of any one of them can spread to the rest. Giving each account a stable, separate IP keeps the accounts as independent as the businesses behind them.
The same separation helps operationally. Your team can hand an account to a colleague together with its proxy line, audit which IP touched which account, and move a client to a new country without touching anyone else's setup. This page covers accounts you own or manage with permission: your own storefronts, your clients' ad accounts, your brand's regional profiles.
There is no single best proxy for multi-account work; the right type depends on how the platform expects the account to behave. A storefront that is logged in from the same warehouse every day wants a permanent address. A profile that lives in a phone app wants a carrier IP. Everything else is well served by a residential IP held for the length of a working session.
On the residential and mobile pools, the country, city and session are set in the proxy username rather than by buying separate endpoints. Give every account its own session identifier and the gateway returns the same IP for that identifier until the session expires: up to 120 minutes on Residential Premium, up to 24 hours on mobile. Reusing the identifier on the next login starts a fresh session, so name it after the account rather than the day.
A practical convention is one credential line per account, stored next to the login itself in your password manager or browser profile. The dashboard's proxy generator produces these lines in bulk, and the REST API does the same from a script, so a hundred accounts get a hundred distinct strings in one call. ISP proxies skip this step entirely: each IP is its own line.
An account registered to a Berlin business should always appear from Germany, ideally from Berlin. ISP proxies cover 25 countries, including the United States, United Kingdom, Germany, France, Canada, Australia and Japan, at country level. The residential pool adds state and city targeting across 200+ countries, and the mobile pool lets you fix the carrier, so a German account can sit on Deutsche Telekom, O2 or Vodafone and a US one on T-Mobile, AT&T or Verizon.
Consistency matters beyond the IP. Set the browser's timezone and language to match the country of the proxy, and keep the same proxy on the account for its whole life rather than switching type halfway. If an account genuinely relocates, change it once and keep the new address.
ISP IPs are billed per address per month with unmetered traffic, so the price is fixed per account: $3.80 each for 1–10 IPs, $3.50 for 11–20, $3.20 for 21–50, $3.00 for 51–100 and $2.50 above 100, minus 5%, 7% or 12% for 60, 90 or 120-day terms. Twenty storefronts on a 90-day term cost $3.50 × 20 × 3 × 0.93 = $195.30.
Residential and mobile are billed per gigabyte, and account management uses little data: logging in, posting and checking dashboards rarely exceeds a few hundred megabytes per account per month. A 25 GB Residential Premium plan at $70 or a 10 GB mobile plan at $35 typically covers dozens of light accounts. The wallet balance never expires and there is no subscription.
Every proxy is a standard HTTP, HTTPS or SOCKS5 endpoint with username:password or IP-whitelist authentication, so it drops into profile-based browsers, automation frameworks, seller tools and plain Chrome. The Chrome extension switches proxies from the toolbar; the REST API creates and lists proxies from your own scripts; the MCP server gives Claude, Cursor and other MCP clients the same access.
Multi-account proxies are for operators of legitimate accounts: agencies with client access, brands with regional storefronts, sellers running several approved stores, teams testing their own product across accounts. Each platform has its own rules on how many accounts one entity may hold; those rules still apply, and a proxy does not change them.
We do not describe our IPs as undetectable and we do not publish success or ban rates, because no honest provider can. What we can promise is a real, consistent address per account, a 99.9% uptime SLA and support that answers 24/7 when a setup question comes up.
| Account type | Proxy type | Session |
|---|---|---|
| Marketplace storefront (Amazon, eBay, Etsy, Shopify) | ISP (static residential) | Dedicated IP, permanent for the whole term |
| Client ad account (Google Ads, Meta Business Manager) | ISP, or Residential Premium sticky | Same IP every login; sticky session named after the account |
| Social profile normally used in a phone app | Mobile 4G/5G | Sticky up to 24 h, same carrier every day |
| Regional brand profile or support seat | Residential Premium | Sticky up to 120 min per working session, city-targeted |
| Research or QA test account | Residential Basic | Rotating, or sticky from 3 min |
| Classifieds listing account per region | ISP (US or local country), or residential city-targeted | Static IP, one per listing region |
It depends on the account. Use a dedicated ISP IP when the account must keep one permanent address, such as a storefront or ad account. Use a mobile carrier IP for accounts normally operated from a phone. Use residential sticky sessions for everything you work on in sessions rather than continuously. Many teams combine all three.
One. The whole point of a multi-account setup is that each account has its own address, so buy one ISP IP per account or assign one session identifier per account on the residential and mobile pools. Sharing one IP between accounts recreates the problem you are trying to solve.
Yes. An account registered to a business in France should be operated from a French IP, and the browser's timezone and language should match. ISP proxies are available in 25 countries; residential proxies add state and city targeting in 200+ countries; mobile proxies let you pick the carrier as well.
With ISP proxies every IP is its own credential line, so you simply paste one per account. With residential or mobile proxies you put a session identifier in the proxy username; the gateway keeps the same IP for that identifier for up to 120 minutes (Residential Premium) or 24 hours (mobile). The dashboard generator and REST API create these lines in bulk.
On ISP proxies, 50 IPs cost $3.20 each, so $160 per month with unmetered bandwidth, or $148.80 per month on a 90-day term with the 7% discount. On residential proxies you pay per gigabyte instead: light account management for 50 accounts usually fits inside a 25 GB Residential Premium plan at $70.
Yes for the residential pool: 100 MB of Residential Basic, valid 5 days, no credit card, unlocked by a one-time SMS verification in the dashboard. ISP and mobile proxies are not included in the trial; the smallest ISP order is one IP for one month at $3.80.
No. A proxy gives each account a real, consistent IP address; it does not change a platform's rules on how many accounts one person or company may hold, and it cannot reinstate an account that was suspended. We do not claim our IPs are undetectable or publish ban rates. Use this setup for accounts you are entitled to operate.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
