What Global Entry and Real ID Actually Are
Global Entry and Real ID are two separate programs managed by the U.S. Department of Homeland Security, but they serve different purposes and are not the same thing. Understanding the difference between them is important because they address different travel and identification needs.

Global Entry is a trusted traveler program that lets U.S. citizens and permanent residents move through customs and immigration faster when returning to the United States from international travel. The program uses biometric technology and background screening to identify lower-risk travelers. When you enroll, you receive a Global Entry card and a known traveler number (KTN). At participating airports, you can use dedicated Global Entry kiosks instead of waiting in standard customs lines. The program also includes the TSA PreCheck benefit, which speeds up security screening at domestic airports.
Real ID is a different program altogether. It is a security standard for state-issued driver's licenses and identification cards. Real ID was established through federal legislation in 2005 as a response to security concerns. States that meet Real ID standards verify the information on applications more thoroughly and include security features on their IDs. A Real ID-compliant license is now required for certain federal purposes, including boarding domestic flights and entering military bases.
The cost difference between these programs is significant. Global Entry currently costs $100 for a five-year membership. Real ID involves no separate fee—it costs the same as a regular driver's license renewal in your state, which varies from $20 to $70 depending on your location. About 42 states and territories now issue Real ID-compliant licenses, as of 2024. Global Entry membership is entirely optional, while Real ID compliance is increasingly necessary for domestic air travel.
Practical takeaway: Before spending money or time on either program, determine which one you actually need based on your travel habits. If you travel internationally several times per year, Global Entry may save you time and stress. If you fly domestically or need a federally-accepted ID, you will need a Real ID-compliant license or an alternative federal ID.
Real ID Requirements and Documentation
Real ID requires state driver's licensing agencies to verify specific documents and information before issuing a compliant ID. The federal government established these standards to create consistency across states and reduce identity fraud. Understanding what documents you need to gather will help you prepare before you visit your state's licensing office.

To obtain a Real ID-compliant license, you must provide proof of several things: your full legal name, date of birth, Social Security Number, and residential address. You must also prove your citizenship or lawful permanent residency status. This is different from a standard license renewal, where documentation requirements are often lighter.
The documents accepted for proving citizenship or residency status include a U.S. passport, passport card, enhanced driver's license, certificate of naturalization, certificate of citizenship, or permanent resident card. If you are a permanent resident who is not yet a citizen, you will provide your permanent resident card. Some states also accept birth certificates along with other forms of identification to establish citizenship. The specific list of acceptable documents varies slightly by state, so checking your state's licensing agency website before your visit can prevent extra trips.
For proving your address, you may use utility bills, lease agreements, mortgage statements, or government correspondence sent to your current address. Most states require documents dated within 30 to 60 days of your application. If you have recently moved, bring mail from your current address.
You will also need to bring an unexpired or expired ID, such as a passport or driver's license. Most states also require a Social Security card or a document showing your Social Security Number. Some states require applicants to appear in person and complete the process at the licensing office, while a few states allow certain renewal applications online if you already hold a valid Real ID.
Fee waivers or reduced fees for Real ID are not generally available through the federal government, though some states offer programs for low-income individuals or seniors. Research your state's specific policies before going to the licensing office.
Practical takeaway: Gather all required documents before visiting your state's licensing office. Create a checklist based on your state's requirements, verify that documents meet the date requirements, and bring originals or certified copies. This preparation prevents delays and multiple office visits.
Global Entry Membership Process and Costs
Obtaining Global Entry membership involves more steps than getting a Real ID because the program includes background vetting and in-person interviews. The entire process typically takes two to four months from initial enrollment to receiving your physical card and membership number.

The first step is submitting an online form with personal information, including your employment history, travel history, and residency information. This is followed by a background investigation conducted by U.S. Customs and Border Protection (CBP). The CBP checks government databases to verify your information and assess your risk level. There is no fee to begin this process or to proceed through background screening.
If your background review is approved or conditionally approved, you will be invited to schedule an in-person interview at a Global Entry enrollment center. These centers are located at major airports and some cities across the United States. During the interview, a CBP officer verifies your identity, reviews your background investigation results, collects your biometric information (fingerprints and photographs), and conducts a brief conversation about your travel habits and history. The interview typically lasts 15 to 20 minutes.
Only after a successful interview do you pay the $100 membership fee for five years. This breaks down to $20 per year or about $1.67 per month. Payment is made online or at the enrollment center. Once payment is processed, you receive a known traveler number (KTN) immediately and can begin using it with airlines. Your physical Global Entry card arrives by mail within two to three weeks.
Global Entry membership automatically includes TSA PreCheck benefits, which means you also gain expedited security screening at over 200 domestic U.S. airports. This combination can be valuable for people who travel both internationally and domestically, as you gain benefits for both types of travel within a single membership.
Practical takeaway: Budget time for the entire Global Entry process—typically two to four months—and do not expect to use the service immediately. If you have an upcoming international trip, start the process at least four to six months in advance. Save your known traveler number once you receive it, as you will use it for every reservation before traveling.
When You Need Real ID for Travel and Daily Life
Real ID requirements have become increasingly important for domestic air travel in the United States. As of May 7, 2025, passengers on domestic flights must present a Real ID-compliant driver's license, state ID card, passport, passport card, enhanced driver's license, or certain military or federal IDs. If you present a non-compliant driver's license, you will be denied boarding, regardless of other valid identification you may carry.

The deadline for Real ID compliance has been extended several times since it was first established in 2005. The most recent extension moved the deadline to May 2025, giving travelers significant time to update their IDs. However, many people have not yet obtained Real ID-compliant licenses, and last-minute trips to licensing offices around the deadline have caused long lines and wait times.
Beyond air travel, Real ID is now required for entering federal buildings, military installations, and nuclear power plants. If your job requires regular access to any federal facility, you will need a Real ID or an alternative federal ID. Federal employees and military personnel may use their federal employee or military ID cards instead of a driver's license for these purposes.
Real ID is not required for other common activities like driving, opening a bank account, voting, or applying for benefits. Many people maintain a non-Real ID driver's license for regular driving and carry a passport when they know they will be flying. However, using a passport at airport security takes slightly longer than using a Real ID-compliant license, and boarding a domestic flight requires presenting one of the accepted forms of identification.
If you hold a passport or passport card, you already have a federally-accepted ID that works for domestic flights. You do not need to obtain a separate Real ID license if you are willing to carry your passport when flying. Similarly, veterans can use military ID cards, and federal employees can use federal employee ID cards for both flights and federal facility access.
Practical takeaway: If you fly domestically or need to access federal facilities, obtain a Real ID-compliant license before your next trip, or use an alternative federal ID such as a passport. Plan ahead by checking the deadline in your state and the current wait times at your local licensing office, especially
