The new normal for caller ID and your company's identity
With the overwhelming flood of robocalling, many spam prevention techniques have been rolling out in the last year or two. Because of this, there is an increasing chance that your caller ID number could get flagged as an at-risk caller. You probably have even seen this on your cell phone, calls from Fraud likely, Scam likey, Telemarketer, or even Spam caller. Call blocking/labeling currently happens at the recipient's carrier. Carriers watch for how many calls they get concurrently or overall from a unique phone number, if it is a disconnected number, and are beginning to use caller ID reputation registries. Additionally, the end-user may use various smartphone apps that crowdsource reports of nuisance calls.
Even if you don't telemarket, scammers can hijack your number and ruin your business phone number's reputation. See our advice below for both telemarketers and business owners.
Register your number with the major caller ID reputation registries.
AT&T, T-Mobile, Verizon, and apps use third-party companies to manage the reputation and verification of business caller IDs. Please follow each guide and check back periodically, as we may add new registration databases as they become available.
Verizon
Verizon maintains an independent database for its Call Filter App. Calling parties and customers who believe a call has been mislabeled as spam or blocked may provide feedback via the link below.

T-Mobile and associated apps
T-Mobile uses the company CallTransparency.com, and on their site, you will need to manually enter each number or upload a CSV file of your numbers and provide your business information. They will call them to confirm they can reach the company name you provided. Make sure you submit all the numbers, go to a welcome recording, IVR, voicemail, or human that will say your company name for them to hear and confirm.
AT&T and associated apps
AT&T and its apps use the Hiya 3 company to manage the reputation and verification of business caller ID. On the site, you will open a support ticket and provide a website listing your company's numbers. Hiya then uses a web crawler for numbers that must be in text / html and not a picture. You will need a phone directory for multiple numbers that lists each user or phone number you want to verify.

First Orion, Hiya, and Transaction Network Services
Recently, a new option has emerged to try and streamline this process. First Orion, Hiya, and Transaction Network Services (TNS) have designed a telephone number registration process for businesses, non-profits, first responders, and other call originators. Legitimate entities will be submitted to each of the companies, and they will, in turn, process the phone number records by the methods mentioned above. This helps with submitting forms, but be aware that each carrier's database still has to process the request and validate the numbers based on the abovementioned methods.
