Founder guide
You've picked a name. Now you have about 48 hours before someone else registers it on a platform you'll want in six months. Here's the fastest, most systematic way to lock it down everywhere — before you start designing a single logo.
The obvious reason to grab handles early is branding consistency — same username everywhere makes you easier to find and harder to impersonate. But there's a less obvious reason that affects you directly if you're building something: social profiles rank in Google search results. If someone else holds @yourbrand on X or Instagram, their profile appears when people search your company name. That's a trust and credibility problem that gets more expensive to fix the longer you wait.
The urgency is real. Popular handles are claimed on a rolling basis by real users, squatters, and bots running automated registrations against domain name databases. If your brand name was just registered as a domain, assume someone is already checking social availability against it.
Register handles before you announce your brand publicly. Once you post about a new venture on LinkedIn or Twitter, it's publicly indexable within minutes. Anyone running brand-monitoring scripts will see it, and the window for snagging your preferred handle on secondary platforms closes fast.
Before you register anything, test your handle against the most restrictive platform constraint: X (formerly Twitter) limits usernames to 15 characters. If it works there, it'll work everywhere. If your brand name is longer, decide now on a consistent short form — and commit to it across every platform rather than using different abbreviations on each one.
When your exact name isn't available, there's a clear hierarchy of acceptable fallbacks. In rough order of preference:
Pick one separator style — underscore or period — and use it consistently. Mixing your.brand on Instagram and your_brand on TikTok creates exactly the confusion you're trying to avoid. Note that X doesn't allow periods in usernames, so if you use a period as your separator you'll need a different convention there anyway.
Every platform has different rules. Getting this wrong mid-registration wastes time and can force inconsistent choices. Here's what matters for each major platform:
| Platform | Username limit | Allowed characters | Key note |
|---|---|---|---|
| X (Twitter) | 15 chars | Letters, numbers, _ | Most restrictive — start here |
| 30 chars | Letters, numbers, _, . | Periods count toward character limit | |
| TikTok | 24 chars | Letters, numbers, _, . | Can't start with a number |
| Facebook Page | 50 chars | Letters, numbers, . | Minimum 5 characters |
| LinkedIn Page | 100 chars (name) | Letters, numbers, - | Custom URL set separately after creation |
| YouTube | 30 chars | Letters, numbers, -, _ | Channel name ≠ handle; both matter |
| 15 chars | Letters, numbers, _ | Same constraint as X | |
| Threads | 30 chars | Letters, numbers, _, . | Linked to your Instagram handle |
| 20 chars | Letters, numbers, _, - | Cannot be changed after set | |
| GitHub | 39 chars | Letters, numbers, - | Relevant if you're shipping software |
One edge case worth knowing: Threads inherits your Instagram handle. If you change your Instagram username, your Threads handle changes too. This means you should treat Instagram as your primary handle and ensure it's the version you want long-term before setting up Threads.
Not all handle locks are equal. Some platforms let you change usernames freely later; others don't. Register the hard-to-change ones first:
Reddit usernames are permanent. There is no edit button, no support ticket path, and no way to reclaim a previous username. If you register the wrong variation, that's it. Do this one first and get it right.
You can set a Facebook Page username freely at first, but once the page reaches 25 followers, the username becomes very difficult to change (requires a formal request to Meta, which is often declined). Set it correctly immediately on page creation, before you promote it anywhere.
These platforms technically allow username changes, but changing them breaks any direct profile links you've shared, can confuse followers, and on some platforms temporarily triggers reduced visibility. Get it right from the start rather than relying on changing it later.
The most time-consuming part of this isn't deciding on a handle — it's hunting down the correct signup URL for each platform, opening each one individually, and tracking which ones you've already done. We built OpenAllTabs specifically to remove that friction.
Select the platforms you need, hit "Open all selected," and every signup page opens in its own tab simultaneously. Tick each one off as you complete it.

X is particularly aggressive about inactive account reclamation. Instagram and TikTok have also removed accounts that showed zero activity over extended periods. A post-once-every-few-months cadence is sufficient to signal genuine ownership.
When you've just created 8 accounts in a row, it's easy to assume you'll remember which email address you used for each one. You won't. Create a simple record — a spreadsheet works — with the platform, username, email address used, and whether 2FA has been enabled. Do this on the same day as registration, not later.
Enable two-factor authentication on every account before you do anything else. Social accounts are high-value targets for impersonation attacks, especially for brands with any public visibility. An authenticator app (not SMS) is the minimum; a hardware key is better for the platforms that support it.
We also built a free account tracker to keep a record of usernames, emails, and 2FA status per platform. Works offline, saves in your browser only, and exports as a file you keep.
This will happen on at least one platform. Your options, in order of how likely they are to actually work:
Beyond the obvious ones (X, Instagram, TikTok, LinkedIn, YouTube), there are a handful of platforms worth registering on purely defensively — even if you have no plans to post there:
OpenAllTabs opens X, Instagram, TikTok, LinkedIn, YouTube, Facebook, Pinterest, Threads, Reddit, Discord, Snapchat, and GitHub signup pages simultaneously — no more hunting for each URL individually.
