You can change your phone number in ADP by calling their support line or asking your HR department to update it for you
If you do not have access to your ADP account password, you have two straightforward paths: contact ADP's customer service directly by phone, or ask your HR or payroll department to make the change on your behalf. ADP keeps your phone number on file for account recovery and paycheck notifications, so updating it does not require you to log in — you just need to verify your identity through other information.
The fastest route depends on whether you remember your username and can answer security questions. If you can do both, ADP's phone support can walk you through the change in minutes. If not, your HR department can update it instantly because they have administrative access to your employee record.
Key Takeaways
- ADP's phone support team can update your number if you provide your username and answer security questions tied to your account.
- Your HR or payroll department can change your phone number directly in the ADP system without needing your password.
- Have your new phone number ready and a quiet place to take the call, since ADP will ask you to verify information before making changes.
- If you changed your phone number because you lost your old phone, tell ADP that during the call so they know why you cannot receive a verification code.
Calling ADP Support to Update Your Number
ADP's main support line is 1-800-225-5237. When you call, have your Social Security number, date of birth, and username ready. The representative will ask you to verify your identity by answering security questions — usually questions you set up when you created your account, like your mother's maiden name or the city where you were born.
Tell the representative you need to update the phone number on your account. They will confirm your new number, repeat it back to you to make sure it is correct, and update it in the system. The change usually takes effect immediately, though it can take a few hours to show up in the app or on the website.
If you do not remember the answers to your security questions, the representative may not be able to complete the change over the phone. In that case, ask them whether you can update the questions themselves, or ask them to transfer you to a supervisor who may have other ways to verify your identity.
Asking Your HR Department to Make the Change
Your HR or payroll department has direct access to ADP and can update your phone number without your password. This is often the fastest option if your company is small enough that you know who handles payroll, or if your HR department has a help desk or ticketing system.
Send an email to your HR contact or submit a request through your company's HR portal if one exists. Include your full name, employee ID number if you know it, and your new phone number. Most departments will update this within one business day.
If you are not sure who to contact, check your most recent pay stub — it usually lists the HR department's phone number or email address. You can also ask a coworker or check your company's internal directory.
What to Do If You Lost Your Old Phone
If you are changing your number because you lost your old phone, tell ADP or your HR department that during the update. This matters because ADP may try to send a verification code to your old number as a security step, and you will not be able to receive it.
When you call ADP support, explain the situation upfront. The representative can skip the code verification or send it to your new number instead. If your HR department is making the change, mention it in your email so they know not to expect a response from your old number.
Updating Your Number in the ADP App or Website Later
Once your phone number is updated in the system, you can manage it yourself going forward. Log into the ADP mobile app or the ADP website, go to your profile or account settings, and look for a section labeled "Contact Information" or "Personal Information." Your phone number will be there, and you can change it anytime you log in.
If you still cannot log in after the phone number is updated, try the password reset feature on the ADP login page. Enter your username, and ADP will send a reset link to your new phone number via text or email — whichever method you set up.
Common Mistakes to Avoid
Do not give your Social Security number or date of birth to anyone who contacts you claiming to be from ADP. ADP will never call you asking for this information — you call them. If someone calls you, hang up and call ADP's official number yourself.
Make sure you have the correct new phone number before you call or email. A typo means you will not receive important paycheck notifications or account alerts. Read the number back to the representative or HR contact to confirm it is right.
If you work for a large company with multiple HR locations or departments, make sure you contact the right one. Some companies have separate payroll and HR teams, and only the payroll team may have access to ADP.
What Happens After Your Number Is Updated
ADP will use your new phone number for text notifications about your paycheck, tax documents, and account alerts. If you set up two-factor authentication on your account, you may need to update that separately — the system will prompt you the next time you log in.
If you were receiving direct deposit notifications or tax form alerts at your old number, those will now go to your new number. You do not need to do anything else — the change is automatic once it is in the system.
Frequently Asked Questions
Can I change my phone number if I do not remember my username?
Yes. Call ADP support at 1-800-225-5237 and tell them you do not remember your username. They can look up your account using your Social Security number and date of birth, then verify your identity through security questions. Once verified, they can update your phone number.
How long does it take for the change to show up?
Changes made through ADP support usually take effect immediately, though it can take a few hours to appear in the app or website. Changes made through your HR department may take one to two business days depending on how often they sync with ADP.
Will changing my phone number affect my direct deposit?
No. Your direct deposit is tied to your bank account information, not your phone number. Changing your phone number only affects how ADP contacts you with notifications and alerts.
What if ADP support says they cannot verify my identity?
Ask to speak with a supervisor, or contact your HR department instead. Your HR department can make the change without needing you to verify your identity over the phone, since they already know who you are.
Do I need to update my phone number in the ADP app separately?
No. Once your number is updated in the ADP system, it automatically updates in the app and on the website. You do not need to change it twice.
