Phone numbers can be mistakenly labeled as "Spam Likely" due to the methods employed by telecom service providers and phone operating systems to identify and protect users from unwanted spam calls. Here's why:

1. Machine Learning Algorithms: Many companies use machine learning algorithms to predict whether a call is spam or not. These algorithms are trained on large datasets of phone calls that have been marked as spam. However, no algorithm is perfect, and there can be false positives, where legitimate calls are incorrectly marked as spam.

2. Number Spoofing: Spammers often use number spoofing techniques, where they mask their actual phone number with a different one when making calls. If a spammer spoofs a legitimate phone number that happens to be yours, that could lead to your number being flagged as spam.

3. Blacklists: Some apps and services use blacklists of known spam numbers. If your number has been mistakenly added to such a list, it may be flagged as spam.

4. User Reports: If enough people report a certain number as spam, it may be flagged as such. This can happen by mistake or if people are reporting the number for the wrong reason.

5. Shared Characteristics: If your phone number shares characteristics with numbers that are frequently used for spam (such as the same area code and prefix), it might be flagged as "Spam Likely".

Service providers and operating systems continuously work on refining their spam detection methods, but mistakes can happen due to these reasons. If your number is being falsely flagged as spam, it's worth contacting your service provider to help resolve the issue.

The carrier algorithms aren’t perfect! Phone calls are being mislabeled as “Spam Risk”, “Scam Likely”, etc. You need to have your phone numbers properly registered, monitored, and have the mislabeling removed. Even phone numbers already in use can be easily remediated. Ytel's number reputation management tool can automatically do this for you.

Branded Caller ID is for companies calling contacts with whom they have an existing relationship. An existing relationship can be in the form of prior communications or if they explicitly requested additional information. It isn't designed for calling contacts with no prior relationship with your brand and isn't likely to improve answer rates in these situations.

Branding will vary depending on the recipient’s device and mobile carrier. Company name and location will always be displayed, while many calls will also display your logo and a reason for your call.
