UnitedHealthcare's main customer service number is 1-877-832-7734, available Monday through Friday, 8 a.m. to 8 p.m. Eastern time.

This number connects you to representatives who handle billing questions, coverage details, claims status, and general account inquiries. Wait times vary by time of day and call volume — early morning and mid-week calls typically move faster than late afternoon or Friday calls.

If you are calling about a specific health plan (Medicare Advantage, employer coverage, individual marketplace plan), have your member ID card ready. The number on the back of your card may route you to a specialized team faster than the main line, depending on your plan type.

Key Takeaways

  • The main UnitedHealthcare customer service line is 1-877-832-7734, open weekdays 8 a.m. to 8 p.m. Eastern time.
  • Your member ID card usually has a plan-specific phone number on the back that may reach the right department more quickly than the main line.
  • For Medicare Advantage plans, UnitedHealthcare Medicare Advantage customer service has separate hours and phone lines listed on your plan documents.
  • Many routine questions — checking claim status, requesting records, updating contact information — can be handled through the UnitedHealthcare member portal or mobile app without calling.

Different numbers for different plan types

UnitedHealthcare operates separate customer service lines depending on your coverage type. If you have a Medicare Advantage plan, employer-sponsored coverage, or an individual marketplace plan purchased through the Affordable Care Act, each has its own phone number and hours.

Check the front or back of your member ID card first — that number is usually the fastest route to someone who handles your specific plan. If you cannot find a plan-specific number, the main line 1-877-832-7734 can transfer you to the right department, though this adds wait time.

For employer plans, some large companies also set up dedicated UnitedHealthcare support lines for their employees. Check your company's benefits website or employee handbook to see if a direct number is listed.

What you can do without calling

UnitedHealthcare's member portal and mobile app handle many tasks faster than a phone call. You can check claim status, view your explanation of benefits (EOB), request copies of documents, update your address or phone number, and see your deductible and out-of-pocket spending without waiting on hold.

To access the portal, go to myuhc.com and log in with your member ID and date of birth. If you do not have an account, you can create one in a few minutes. The mobile app (UnitedHealthcare Mobile) offers the same features and works offline for some functions.

For prescription questions, you can also contact your pharmacy directly or use the UnitedHealthcare pharmacy support line, which is sometimes faster than the general customer service line.

When you might reach a wait or get transferred

Call volume spikes on Monday mornings, the first few days of each month, and around the time bills are due. If you call during these windows, expect 15 to 45 minutes of wait time depending on the time of day.

If your question involves a claim dispute, prior authorization, or appeals, you may be transferred to a specialized team. Have your claim number or authorization request number ready — this helps the representative find your case faster and reduces the chance of being transferred again.

Some issues, like appeals of denied claims, have their own dedicated lines and processes. The representative who answers the main line can tell you whether your question needs a transfer and provide that number directly.

International and TTY access

If you are calling from outside the United States, UnitedHealthcare has international customer service numbers that vary by country. Check your member documents or the UnitedHealthcare website for the number that serves your location.

For TTY (text telephone) access, call 1-877-832-7734 and ask the representative to transfer you to TTY services. Some UnitedHealthcare plans also list a TTY number directly on the member ID card.

What information to have ready before you call

Calls move faster when you have your member ID number, date of birth, and the specific question or claim number written down. If you are calling about a claim, have the date of service and provider name available. If you are calling about a bill, have the statement in front of you.

If you are calling on behalf of someone else, have their member ID and written permission to discuss their account. UnitedHealthcare will not release information to a third party without authorization, even a family member.
