"How many proxies do I need?" has no single answer, but it does have a method. The right number depends on what each IP is doing: holding one identity, carrying a share of scraping requests, or giving a team a fixed address to allowlist. Buy too few and you overload IPs or mix identities; buy too many and you pay for addresses that sit idle. This guide gives you a way to count for each common situation, then shows how to buy in a way that lets you correct the number later.

## Start with the job each IP does

Every proxy in your setup falls into one of three roles. Sizing is different for each.

| Role | What one IP represents | How to count |
|---|---|---|
| Identity | One account, browser profile or device | One IP per identity, plus spares |
| Throughput | A share of request volume | Total request rate divided by a safe rate per IP |
| Fixed access | A stable address a service trusts | One per location or per tool, plus a backup |

Mixed setups are common. An agency might need identity IPs for client accounts and a few throughput IPs for rank tracking. Count each group separately, then add them up.

## How many proxies do I need for accounts and profiles

For account-based work such as social media management, marketplace seller accounts or ad accounts, the usual rule is one IP per account or per browser profile. The point is consistency: an account that always appears from the same address looks like a person with a stable connection, while several accounts sharing one IP look linked. A [dedicated proxy](https://cloudj.net/blog/dedicated-proxy-guide) suits this because the IP is assigned to you alone and stays the same for the whole term.

A worked example:

- 12 client accounts across two platforms
- 2 staff members who also log in to an internal tool from home
- Spares: about 10 percent, rounded up, so you can replace an IP without waiting

That gives 12 identity IPs, plus 2 spares, for 14. The staff logins usually do not need proxies at all unless the internal tool requires a fixed IP, in which case they belong in the fixed-access group.

Two notes. First, keep each account on its own IP over time; constantly moving accounts between IPs defeats the purpose. Second, a proxy does not prevent bans or override platform rules. Follow each platform's terms on multiple accounts, and see [antidetect browsers with proxies](https://cloudj.net/blog/antidetect-browser-proxy) or [proxies for social media agencies](https://cloudj.net/blog/social-media-agency-proxy) for setup patterns.

### Choosing the IP type per identity

Cloudj's dedicated IPv4 proxies are static addresses registered to an ISP, available in all seven proxy countries and fast and stable for most work. Where you specifically want an address from a home-broadband provider, a static residential ISP proxy is the other option; Cloudj offers those in the United States and Vietnam. Neither type promises that a platform will accept an account. The [datacenter vs static ISP comparison](https://cloudj.net/blog/datacenter-vs-static-isp-proxy) helps you split your count between the two.

## How many proxies for scraping and monitoring

For throughput work you size by request rate, not by identity. The formula is simple:

```text
IPs needed = peak requests per minute / safe requests per minute per IP
```

The hard part is the denominator. No universal "safe rate" exists; it depends on the target site, the pages you request and how your client behaves. Find it empirically:

1. Start with a handful of IPs and a conservative rate per IP.
2. Watch status codes. Rising 429 (too many requests), 403 or CAPTCHA pages mean you are above the site's tolerance.
3. Raise the rate slowly until errors start, then step back and use that lower figure.

A worked example with illustrative numbers: you need to check 30,000 product pages every 6 hours. That is 5,000 pages per hour, or about 84 per minute. If testing shows a site is comfortable with around 6 requests per minute per IP, you need 84 / 6 = 14 IPs. Add a margin for retries and slow periods, roughly 20 percent, and plan for 17.

Concurrency matters as well. If each IP serves one worker at a time, the number of IPs also caps how many parallel workers you run. The [Python scraping with proxies guide](https://cloudj.net/blog/python-scraping-proxy) and [Playwright and Puppeteer with proxies](https://cloudj.net/blog/playwright-puppeteer-proxy) show how to assign proxies to workers. Always respect the target site's terms and robots rules, and avoid loads that affect the site's normal users.

## How many for location coverage and fixed access

Some needs are about where the IP is, not how many requests it carries:

- **Geo testing and ad checks.** Usually one or two IPs per country you test. Cloudj proxies are available in Vietnam, the United States, Japan, South Korea, Singapore, Hong Kong and the United Kingdom.
- **IP allowlisting.** One IP per tool or team that needs to reach an allowlisted service, plus one backup so a single change does not lock you out. The [static IP allowlisting guide](https://cloudj.net/blog/static-ip-allowlisting-proxy) covers this pattern.
- **Local rank tracking.** Size by the number of locations and keyword checks per day, using the throughput formula per country.

## Common sizing mistakes

- **Sharing one IP across many identities to save money.** It is the cheapest choice up front and the most expensive one when accounts get linked.
- **Sizing scrapers for average load.** Size for the peak window, because that is when blocks happen.
- **No spares.** Without a spare you have nowhere to move an account or worker while an IP is being replaced.
- **Buying the final number on day one.** You learn the real safe rate only after testing.

## Buying in a way that lets you adjust

The practical approach is to start smaller than your estimate, measure, then add. On Cloudj that works because ordering is self-service in the [console](https://app.cloudj.net), paid from your balance, and proxies are ready in a few minutes. A few facts help with planning:

- One order can contain anywhere from 1 to 1,000 IPs.
- Larger orders get a lower price per IP through quantity tiers, so once you know your number, consolidating into a bigger order can make sense. The console shows the per-IP price live as you change quantity.
- Terms are 1, 3, 6 or 12 months, and auto-renew from your balance keeps the same proxies running.
- Within 24 hours of ordering you can stop an order and get the unused part back, which is a useful safety net for a first test batch.

Test each new batch before putting it into production; the [curl testing guide](https://cloudj.net/blog/test-proxy-curl) shows a loop that checks a whole list at once.

## FAQ

### Is one proxy enough?

For a single account, one tool that needs a fixed IP, or occasional geo checks, yes. For several accounts or any steady scraping, you will need more.

### Should every account get its own proxy?

That is the common practice for account work, because it keeps each account's IP consistent and separate. Follow each platform's rules on multiple accounts.

### How many spare proxies should I keep?

About 10 to 20 percent of your active count is a reasonable starting point, and at least one.

### Do more proxies make scraping faster?

They let you run more parallel requests without overloading any single IP. The real limit is how much load the target site tolerates.

## Plan your first order

Count your identities, estimate your peak request rate, add spares, then start with a test batch. You can see the countries and types on the [proxy overview](https://cloudj.net/proxy-ipv4) and live per-IP prices on the [pricing page](https://cloudj.net/pricing) before ordering.
