No doubt about it—spam calls and texts are annoying. But if you’re not paying attention, they can also be dangerous.
According to the National Consumer Law Center, Americans receive more than 33 million spam calls every day. These can range from benign telemarketing calls to malicious attempts by hackers to swipe your personal and banking information.
In this article, we'll explain why this problem is so common and provide strategies for how to stop spam calls and texts in their tracks.
Spam calls and texts are unsolicited communications from companies, individuals, or scammers that aim to get you to reply to the caller or click a link in a text message.
Here are just a few ways that spammers try to bait people into responding or providing money and personal information:

While blocking numbers can be effective, it can also be tedious, especially if the spammers keep changing their numbers. Fortunately, there are other methods if this one doesn’t solve the problem.
If you're getting a lot of spam from unknown numbers, you can often filter these calls so they go straight to voicemail in your phone settings. Some phones, like the Google Pixel, have a specific Call Screening feature built in, as noted below.
Here’s how to stop spam calls and texts with filters:

The above methods ensure you won't be interrupted by calls from people who aren't in your contacts, but it also means you might miss important calls from unknown numbers.
Some of these features may work better with newer smartphones with the latest software updates, so if you need an upgrade, Navi can help. Our free and unbiased Phone Deal Finder below can help you find the best phone deals on the latest iPhone or Android device of your choosing.
Call filtering apps can provide a more thorough solution to stopping spam than blocking individual numbers one by one.
Many carriers offer spam-blocking apps, which can be effective at filtering unwanted calls and texts. Below are a few examples:
Several third-party apps also specialize in blocking calls and texts from spam numbers. Some popular options include:
Choose an app that's well-reviewed and available on the Apple App Store or Google Play.
One of the easiest ways to prevent spam is to be careful where you share your number. Avoid posting it on social media or any public website.
If you need to enter your number online, make sure the site is secure—look for the padlock icon in the address bar, which indicates SSL certification.
The National Do Not Call Registry is a free service that can help reduce telemarketing calls. Visit donotcall.gov and enter your phone number to sign up for the Do Not Call List. You should start receiving fewer spam callers in about a month.
While it won't stop all unsolicited calls, since political groups, charities, and debt collectors can still reach you, it's a good first step toward protecting your privacy.
Scammers often pose as IRS agents and use pressure tactics to steal financial information. If you get a call claiming to be from the IRS, ask for a reference number, hang up, and call back using an official IRS number to check the claim.
Also, never click on links from "urgent" IRS texts or emails since these are common phishing attempts. Remember, the IRS will never ask for personal details via email, text, or social media. Call the IRS directly at 1-800-829-1040 if something seems off to confirm if the contact is legitimate.
Even with all these strategies, some spam calls and texts may still slip through to you, so it's important to recognize their telltale signs so you can avoid falling for phone scams.
Here are some red flags to watch out for:
If you're ever in doubt about the legitimacy of a call or text, ignore it. Don't answer unknown numbers or click on any links in questionable texts.
Instead, you can look up the number online to see if others have reported it as spam.
Despite your best efforts, it’s possible you might still fall for a scam. If you've given out personal information or money to a scammer, here's what you should do next:
Contact Your Bank: If you've provided your bank account information, contact your bank immediately to report the fraud and freeze your accounts if necessary. Many banks also offer the option to freeze your cards right from their smartphone app.
Change Your Passwords: If you've given out your email address or other online account information, change your passwords immediately. Make sure to use strong, unique passwords for each account. That means passwords that are a mix of letters, numbers and symbols, if possible. Use a password app like LastPass or 1Password to organize your passwords.
Monitor Your Credit: Monitor your credit reports for any unusual activity. You can get a free credit report once a year from each of the three major credit bureaus (Experian, Equifax, and TransUnion) at annualcreditreport.com.
Report the Scam: You can report spam calls to the Federal Communications Commission or the Federal Trade Commission (FTC). They can take action against companies that violate telemarketing rules, and your report might help prevent others from being targeted.
Spam calls and texts are an unfortunate reality in today's world, but that doesn't mean you have to put up with them.
By understanding why you are getting so many spam calls and texts and how to stop getting them, you can protect your personal information and reduce the annoyance they cause. And remember, when in doubt, it's always safer not to answer unknown numbers or click on suspicious links.
One way to stop spam calls is to dial 1-888-382-1222 from the phone you want removed. Your number will be taken off the Registry by the next day, but businesses may take up to 31 days to update their call lists.
It’s best to ignore spam calls. Declining them can signal that your number is active, which might lead to even more spam. Avoiding picking up is your best option.
Picking up a spam call lets scammers know you’re an easy target, encouraging them to keep trying. They’ll often call back from new numbers, hoping to get you on the line again. The more you answer, the more likely you will get flooded with unwanted calls.
