It seems like the practical move. You want brands to reach you easily. Email feels slow. A phone number in your bio signals you are open for business, reachable, serious.
And it works. Brands do call. Agencies do text. Partnership requests do come in.
So does everything else.
Because the moment a phone number is in a public bio, it is no longer functioning as a professional contact for brands. It is a public piece of data sitting on a platform with hundreds of millions of users, accessible to every data scraper, spam operation, and bad actor that monitors those platforms continuously.
The brand deals are real. So is everything that comes with them.
What Happens to a Number in a Public Bio
Social media bios are public by default on most platforms. This means they are indexed by search engines, accessible without an account, and scannable by automated tools that collect publicly available data at scale. Data brokers specifically monitor social media profiles for contact information. A phone number appearing in an Instagram, TikTok, or YouTube bio can be collected and added to contact databases within hours of being posted. From there it can be sold to marketing companies, spam operations, robocall services, and in some cases to people with malicious intent.
This is not theoretical. The same mechanism that allows a brand manager to find your number allows anyone else to find it too. The platform does not distinguish between the two. It is a public field and it is treated as one. Once the number is in those databases it does not leave because you updated your bio. Data that has been collected and sold circulates independently of its original source. Removing the number from your profile stops new collection going forward but does nothing about the copies already distributed.
The Specific Risks Creators Face That Most People Do Not
Creators face a version of the phone number exposure problem that is more intense than the average person’s, for a specific reason: they deliberately cultivate a large, mixed audience of people they have never met and never will. Most of that audience is great. But an audience of any significant size will statistically include people whose attention becomes a problem. A small percentage of followers who become fixated, who read every post, who take the presence of a phone number as a direct personal invitation, and who do not understand the boundary between a parasocial relationship and an actual one.
A number in a public bio does not just attract brands. It attracts everyone who sees the bio, which on a platform like Instagram or TikTok can be an enormous and varied group. The creator who put their number there for brand managers to call is also the one who starts receiving texts at midnight from followers who found the number, from account hijacking attempts that use the number as a social engineering tool, and from spam and scam operations that specifically target creators because they are often high value targets with brand relationships, payment accounts, and significant platform access.
There is also the SIM swap risk, which we covered in detail in our blog on what someone can actually do with just your phone number. For a creator, the risk is elevated because a successful SIM swap against a creator can give an attacker access to brand payment accounts, affiliate links, and platform accounts that use the phone number for two factor authentication. The number in the bio is the starting point for this kind of targeted attack.
What Brands Actually Need: Less Than You Think
Here is something worth knowing if you are putting a phone number in your bio specifically to attract brand deals. Most brand managers and agency partnership teams do not initiate contact by phone. They email. They use platform DMs. They fill in collaboration forms linked from bios. A phone number in a bio is primarily useful to people who want to reach you immediately without going through any normal professional channel. Some of those people are brands in a hurry. Many more are not.
The standard professional approach for creator outreach is an email address in the bio, a link to a media kit or collaboration page, or a booking link through a managed tool. These create the same accessibility for legitimate brand contacts while not creating a public, scrapable piece of personally identifying information.
A second phone number, if you want one in your bio at all, gives you the best of both. It functions as a real number for anyone who texts or calls it. Calls connect, texts arrive. The difference is that it is not the number tied to your personal accounts, your banking, your family, and everything else your real number is connected to.
The Scraping Problem Specific to Creator Bios
Social platforms are particularly high value targets for scraping because creator bios are structured, consistent, and updated by the creators themselves to be easy to read. A phone number in a bio is almost always formatted as a standard number, preceded by a call to action like “for collabs text me” or “business enquiries.” This makes it trivially easy for automated tools to identify, collect, and categorise.
Unlike a number buried in a conversation thread or hidden behind a contact form, a bio number is sitting at the top of a public profile with a label explaining exactly what it is for. It is the most findable version of a phone number that exists online.
The creator economy is large and growing. With paid partnerships on TikTok and Instagram now accounting for a significant share of posts, brand deal volume has become commercially interesting enough to attract both legitimate brand managers and operations that harvest creator contact details to build commercial lists. Your number in your bio is entering a more complex ecosystem than it might appear.
A Better Setup for Creator Contact
The cleanest professional setup for most creators who want to be reachable for brand deals without exposing their personal number looks like this.
A business email address in the bio, formatted clearly and separately from any personal email. This is the primary contact point for serious brand enquiries and it functions exactly as well as a phone number for most outreach.
A second phone number if you want to offer a text or call option. This number receives calls and texts normally. You answer brand calls on it exactly as you would on your real number. The difference is that your real number is not the one sitting on a public profile being collected continuously by automated tools.
A link to a media kit or collaboration page where brands can submit structured enquiries, see your rates and reach statistics, and initiate contact in a way that filters serious enquiries from noise.
This setup is more professional than a personal number in a bio and it is more protective. It signals to brands that you run your creator work with the same seriousness you would bring to any other business.

If Your Personal Number Is Already in Your Bio
If you have had your real number in a public bio for any length of time, removing it going forward is still worth doing, though it will not undo what has already been collected.
Remove the number from your bio and replace it with a business email or a second number going forward. This stops new collection from that source.
If you have been receiving unusual contact, spam calls, or messages that feel targeted rather than generic, this may be a sign that the number has already entered commercial or malicious databases. Our blog on why spam calls keep coming and what actually reduces them covers the practical steps for managing a number that is already in circulation.
If you have concerns about specific individuals from your audience making unwanted contact, our blog on what to do when someone will not stop texting or calling you covers the steps that actually help in that situation.

Frequently Asked Questions
Should I put my phone number in my Instagram or TikTok bio for brand deals?
Not your personal number. A phone number in a public bio is immediately accessible to automated data collection tools and data brokers, not just to brand managers. Once collected, it enters contact databases that circulate independently of whether you later remove it from your profile. A second number in your bio gives brands the same accessibility without exposing your personal number to continuous public collection.
Do brands actually call creators directly from a bio number?
Most legitimate brand partnership teams initiate contact by email or platform DMs rather than by calling a bio number directly. A bio phone number is more useful to spam operations and unsolicited contact than it is to serious brand managers who are following normal professional outreach processes. A business email address or a link to a collaboration page serves brand contact purposes as effectively as a number, with far less exposure.
What is the risk of a creator’s phone number being used in a SIM swap attack?
A creator whose phone number is publicly available is a more attractive SIM swap target than a private individual because a successful attack can give access to brand payment accounts, affiliate earnings platforms, and social media accounts that use the phone number for two factor authentication. The public number reduces the effort needed to initiate the attack. Keeping your real number out of public profiles meaningfully reduces this specific risk.
Can I use a second number for creator business contact?
Yes, and it is the cleanest solution for most creators who want to offer a contact number for brand enquiries. A second number works exactly like a real number for calls and texts. Brand managers who call it reach you normally. The difference is that your personal number, with its connections to your banking, personal accounts, and private identity, is not the one sitting in a public profile.
If I remove my number from my bio, is the damage already done?
Removing the number stops new collection from your profile going forward. It does not remove copies already collected and distributed to data broker databases. The number will continue to appear in those databases for some time after removal, which means spam and unsolicited contact may continue at some level. Replacing it with a second number, rather than simply removing all contact options, ensures legitimate brand contacts still have a way to reach you while limiting further exposure of your real number.
