How do spam callers get your number in the first place?

Spam calls have become a pervasive issue in today's digital age, inundating people with unwanted notifications and potential scams. To understand how your number ends up on spammer's lists, it's essential to know the various ways your information is collected and shared. Many of these causes are beyond your control, including random robocaller dials and data breaches.

Data breaches are a significant source of stolen numbers, often resulting from security lapses at websites or services you've used. If a company you've signed up with suffers a breach, your phone number can be exposed, making it available to spammers. Additionally, your number may have been randomly dialed by illegal robocallers or obtained from public records like court directories, property deeds, or corporate filings.

While registering with the FTC's Do Not Call Registry can help limit telemarketing calls, it doesn't prevent all spam. Exempt callers such as charities, political parties, debt collectors, and surveyors can still reach you. Most available numbers are bought from data brokers who legally resell your information to third parties after you sign up for various accounts, loyalty programs, contests, or sweepstakes.

You may have unknowingly agreed to these sales when using services or websites, or through phishing scams where you provide your information on fake pages.

To protect yourself, be cautious with the sites you visit, avoid suspicious ones, and search for reviews and scam reports before signing up. Hide your number on public profiles and be mindful of the accounts you create, as well as the checkboxes you tick. If you're experiencing persistent robocalls, registering with the FTC's Do Not Call Registry can help limit your exposure.

To find out how your number may have been exposed, check if an associated account was part of a data breach using sites like Have I Been Pwned, or search for your phone number in quotes online.
