AARP membership starts at age 50, and that's the only age requirement

You become a member of AARP the moment you turn 50. There is no minimum income, no health requirement, no background check. Age 50 is the single threshold that matters. You can join online, by phone, or by mail, and membership begins when ready after AARP processes your payment.

The reason AARP chose 50 instead of 55 or 65 is partly historical—the organization was founded in 1958 when life expectancy was lower and retirement patterns were different—but also practical. At 50, many people start thinking about the second half of their working life, healthcare costs, and what comes after full-time work. AARP's programs and discounts are built around that timeline.

You do not have to be retired to join. You do not have to be on Medicare. You do not have to own a home or have savings. If you are 50 or older, you can join.

Key Takeaways

  • AARP membership is open to anyone age 50 or older, with no other requirements tied to income, employment status, or health.
  • You can join at 50 whether you are still working full-time, part-time, or retired.
  • Membership costs a flat annual fee and renews each year on the anniversary of your join date.
  • Some AARP programs and discounts have their own age requirements (like Medicare-related services at 65), but basic membership itself requires only that you be 50.

Why AARP picked 50 as the membership age

AARP was founded in 1958 as the American Association of Retired Persons, which is why the acronym stuck even after the organization dropped "Retired" from its official name in 1999. The original age of 55 reflected retirement patterns of that era. Over time, as people worked longer and life expectancy increased, AARP lowered the threshold to 50 to capture people in their late working years who were beginning to plan for what came next.

The organization reasoned that financial planning, healthcare decisions, and caregiving concerns often surface in the early 50s, even for people who plan to work into their 60s or 70s. By starting membership at 50, AARP could reach people before they retired, not after.

What changes when you turn 65

Turning 65 does not change your AARP membership status or cost. You remain a member at the same annual rate. However, 65 is when certain AARP programs and services become relevant because it is the age Medicare may be able to access begins.

AARP offers Medicare education, plan comparison tools, and advocacy around Medicare policy. These services are built for people 65 and older because that is when Medicare enrollment opens. If you join AARP at 50, you can use the organization's general resources—discounts, advocacy on age-related issues, financial planning guides—but Medicare-specific services will become available to you at 65.

How membership works across different life stages

AARP treats all members the same way regardless of whether you are 50, 65, or 85. You pay the same annual membership fee. You get access to the same discounts, publications, and online resources. The difference is which of those resources matter most to you at each stage.

At 50, you might use AARP's resources on caregiving (many people in their 50s are supporting aging parents), workplace age discrimination, and long-term financial planning. At 65, you might focus on Medicare, Social Security, and healthcare costs. At 75 or 80, you might use resources on living arrangements, end-of-life planning, and managing multiple medications.

But the membership itself does not change. You do not graduate to a different tier or pay more as you age. AARP's model is that once you are in, you stay in at the same cost.

Joining before you retire versus after

Many people join AARP years before they retire, and many join after they have already stopped working. There is no advantage to joining at one time versus another—the membership is the same either way. Some people join at 50 because they want to start exploring retirement planning early. Others wait until 62 or 65 because that is when retirement feels imminent or real.

The main reason to join sooner rather than later is access to discounts and resources while you are still working and earning income. AARP discounts on travel, dining, shopping, and services can add up over time. But if you prefer to wait, there is no penalty for joining later.

Membership renewal and what happens if you let it lapse

AARP membership renews annually on the anniversary of the date you joined. You will receive a renewal notice in the mail and by email before your membership expires. If you renew on time, there is no gap in your membership.

If your membership lapses—because you did not renew or chose to let it end—you can rejoin at any time by paying the current annual fee. There is no waiting period, no re-process process, and no penalty. You straightforward pay and your membership restarts. Your age remains the only requirement.

Frequently Asked Questions

Can I join AARP at 49 if my birthday is coming up soon?

No. AARP requires that you be 50 at the time you join. You can sign up on the day you turn 50, but not before. Some people set a reminder to join on their 50th birthday.

Do I have to be retired to join AARP?

No. You can be working full-time, part-time, or retired. Age 50 is the only requirement. Many AARP members are still in the workforce.

Does AARP membership cost more if I join at a later age?

No. The annual membership fee is the same whether you join at 50 or 80. AARP does not charge more based on age.

What if I join AARP and then move to another country?

AARP membership is available to U.S. residents and U.S. citizens living abroad. If you move outside the United States permanently, contact AARP to discuss your membership status, as some services may not be available internationally.

Can I give an AARP membership as a gift to someone who is 50?

Yes. You can purchase a membership for someone else as long as they are 50 or older. AARP will send them a welcome package and membership materials. The recipient can then manage the renewal themselves.
