Every social media account has a permanent unique ID assigned by the platform. Even if the username changes, this ID stays the same. During AccoSwap escrow transactions, account IDs are used to verify that the exact correct account is being transferred.

Sell My Account on AccoSwap →Picking a consistent username across every platform is one of the first steps to building a recognisable brand. Our free username availability checker queries YouTube, TikTok, Instagram, Twitter/X, Facebook and Telegram at the same time, so you can instantly see where your desired handle is still free and where it has already been claimed.
Whether you are launching a new channel or planning to buy an existing account on AccoSwap, knowing username availability up front saves you time and helps you avoid rebrands later. The tool requires no login and never stores the usernames you check.
Behind every public username is a permanent numeric or alphanumeric ID that the platform assigns when the account is created. Unlike the handle, this ID never changes — even if the owner renames the account. Our ID finder extracts that identifier from any profile URL or handle in a single click.
Account IDs are essential during ownership verification. On AccoSwap, escrow uses the account ID to confirm that the exact channel or profile agreed upon is the one actually being transferred, protecting both buyers and sellers from mix-ups or fraud.
Not sure what your YouTube channel, TikTok or Instagram account is worth? The estimator combines follower count, engagement rate, account age, monthly revenue, niche and monetisation status to produce a real-time valuation range that updates as you move each slider.
It is designed as a starting point for pricing — high-demand niches such as finance and business carry stronger multipliers, while monetised and verified accounts command a premium. For real market benchmarks, compare the estimate against completed sales in the AccoSwap marketplace.
The checker queries each platform's public profile page in real time, so results reflect current availability. Some platforms rate-limit automated requests, so an occasional "could not verify" result simply means you should try that platform again in a moment.
No. All three tools — the username checker, ID finder and value estimator — are completely free and require no sign-up or login. You only need an AccoSwap account when you are ready to actually buy or sell.
A YouTube Channel ID (it starts with "UC") is the channel's permanent identifier. It is used by APIs, verification systems and escrow services to reference the exact channel regardless of any name changes — which is why it is so important when transferring ownership safely.
The estimator weighs followers, engagement, account age and monthly revenue, then applies multipliers for niche, platform, monetisation and verification. The result is an indicative range, not a fixed price — final value always depends on real buyer demand.
Absolutely. Once you have checked your username and estimated your value, you can list your account for free on AccoSwap. Every sale is protected by secure escrow, so payment and account transfer happen safely for both sides.
