Why Is My Business Number Marked as a Spam Call? How to Fix Spam Call Labelling on Mobile Phones

Have your clients or partners reported seeing your business number flagged as a “spam call” when you try to reach them? If so, you’re not alone. Recently, some UK businesses have experienced issues with legitimate phone numbers being incorrectly marked as spam—particularly when calling Samsung Android smartphones. This can negatively affect your ability to connect with customers and may even damage your professional reputation. Here’s what’s causing it and how to resolve it.

What Causes Legitimate Numbers to Show as Spam Calls?

With the rise in nuisance and spam calls, mobile service providers and smartphone manufacturers like Samsung have implemented systems to protect users. These systems rely on third-party databases and caller ID technology to flag potentially fraudulent or spoofed numbers.

However, sometimes legitimate UK business numbers—including those starting with 01, 02, or 03—are mistakenly listed as potential spam. This typically occurs when your number hasn’t been properly registered with the databases these systems use to verify trustworthy callers.

Why This Issue Affects Samsung Android Devices

Samsung devices in particular use a third-party system called Hiya/SMART to filter spam calls. If your number isn’t listed or verified in Hiya’s database, Samsung phones may automatically label your calls as spam—even if your business is genuine and your number has never been used for marketing or cold calling.

How to Remove the Spam Call Label from Your Business Number

Fortunately, resolving this issue is straightforward. You can request to update your business number’s reputation status using a simple online form. This ensures your number is marked as legitimate and no longer flagged as a spam call on Samsung phones.

You’ll be asked to provide your contact details and explain that your number is being incorrectly flagged as a spam call. Once processed, your number should be updated across Samsung’s spam filter systems.

Why It’s Important to Act Quickly

When your business number is marked as a spam call, it can lead to missed opportunities, damaged client trust, and reduced contact rates. By proactively addressing the issue, you not only improve communication but also protect your brand’s reputation.

Can caller ID systems mistakenly label business numbers as spam calls?

Yes, caller ID systems can mislabel business numbers as spam. These systems rely on automated algorithms and third-party data. If your number lacks verification or hasn’t built a positive call history, it may get flagged—regardless of how responsibly your business uses it.

What types of businesses are most at risk of being flagged as spam callers?

Businesses that place frequent outbound calls, such as sales teams, appointment reminders, or customer support centers, face a higher risk. Carriers may interpret high call volumes—especially to new contacts—as spam-like activity if the number isn’t recognized or trusted.

How can I monitor whether my business number is being flagged as spam?

You can track your number’s reputation by calling various mobile devices and carriers, asking clients how your number appears, and using third-party call analytics tools. These tools help you identify whether networks flag your number and let you respond before it affects client communication.

Does changing my business number help if I’ve been flagged as a spam caller?

Switching numbers may offer a temporary fix, but it often creates more problems. A new number won’t solve the core issue unless you verify and register it properly. Instead, focus on improving your current number’s reputation by registering it with trusted caller ID databases and following ethical outbound call practices.
