7 Costco Membership Rules South Carolinians Get Turned Away For

South Carolina is home to eight Costco warehouses, and every one of them enforces membership rules strict enough to send a paying customer back out the door.

The reasons run stranger than many shoppers expect.

These are the Costco rules that catch South Carolina members—and their guests—off guard.

1. The Face-to-Card Match

Costco checks the person at the door against the person on the card.

That’s true at every one of South Carolina’s eight warehouses, from Spartanburg to Myrtle Beach.

An entry scanner pulls up a member’s photo the moment a member taps or scans the card, and an attendant checks that photo against the face standing there before waving anyone through.

A digital card in the Costco app works the same way at the scanner as the plastic one.

No photo on the card?

Costco asks for a government-issued photo ID that matches the name on the account, and a passport or a driver’s license both work.

Show up without either one, and the line stops right there.

2. Another Scan at the Register

Costco doesn’t stop checking at the front door.

Costco checks the same card again at the register or the self-checkout screen before a purchase goes through, a second look built to catch a card that only got someone past the entrance.

Costco started asking self-checkout shoppers to match their face to their card in September 2024, around the same time entrance scanners began reading every card at the door.

A shopper who talked their way past the entrance on someone else’s account still hits a wall at the belt.

Membership doesn’t split between two people this way.

One card, one person.

3. No Guests Without a Member

Costco lets a member bring up to two guests through the door on any single visit.

The catch is where that guest has to be standing when the entrance scanner reads the card.

Costco requires a guest to enter alongside the member who invited them, not slip in separately to meet up once they’re already inside.

A guest who shows up on their own, planning to find the member somewhere in the aisles, hits a wall at the entrance instead.

Once inside, the rule stays the same for the whole trip: A guest stays with the member, not splitting off toward electronics while the member heads for produce.

Two guests, one door.

4. Costco’s Members-Only Pumps

Costco limits every fuel island to paying members.

A shopper has to tap or scan an active membership card at the pump before it accepts payment, whether that’s a Gold Star, Executive, or Business account.

A guest riding along cannot fill up on their own, even sitting in the passenger seat while the member pumps a different car nearby.

The accepted list stops at Visa cards, debit cards, and Costco Shop Cards. Cash isn’t on it.

There’s one workaround.

A member can load money onto a Costco Shop Card ahead of time.

A non-member holding that Shop Card can pump gas on their own, since the card itself carries the value instead of a membership scan.

No card, no gas.

5. A Membership Card for Glasses and Contacts

Costco lets a non-member book an eye exam at its Optical department, no membership card required to sit in the chair.

The card matters at the next step.

Costco requires an active membership to complete a glasses or contacts purchase, even for the same shopper who just finished the exam.

A shopper who skipped the membership desk walks out with a prescription and nothing to fill it with.

The exam skips the card.

The glasses don’t.

6. Before 10, Not for Everyone

Costco reserves the first hour of most shopping days for one membership tier.

Executive members get in from 9 to 10 a.m. on weekdays and Sundays, and 9 to 9:30 a.m. on Saturdays, before the doors open to everyone else.

Costco turns back a Gold Star member who shows up at 9:15 for a quick trip.

Not close enough.

The food court and the pharmacy follow the same early window on weekdays and Saturdays, so even a prescription pickup waits until 9 a.m.

Sunday is the exception: Costco’s pharmacies stay closed all day, early hours or not, no matter which tier a member holds.

7. Membership for Beer and Wine

South Carolina Costco warehouses keep beer and wine behind the same membership check as everything else on the floor.

Several states require any retailer holding a public liquor license to sell to the general public, not just to members. Connecticut is one of them, and many Costco locations there run the liquor department through a separate outside entrance that skips the membership check entirely. South Carolina doesn’t have that carve-out.

A non-member who fills a cart with a six-pack still needs an active card to check out, the same as with paper towels or a rotisserie chicken.

Spirits work differently.

Several South Carolina Costco locations, including the Columbia and Charleston-area warehouses, sell hard liquor through an attached store with its own outside entrance, and that separate liquor room doesn’t ask for a membership card.

Two doors, different rules.

Household Card vs. Guest Pass

Costco doesn’t sell a trial membership, a day pass, or a free shopping pass to anyone in South Carolina, whatever an old email forward claims.

The one workaround Costco offers is a free household card, issued to one other adult who lives at the same address as the primary member.

That second person gets their own card with their own photo, and they can shop, pay, and use the food court entirely on their own, no guest limit and no accompaniment rule attached.

A roommate, a grown child, or a partner who isn’t married to the primary member all qualify, as long as the address matches and they’re at least 16.

A membership caps out at two names total, primary and household, so a third person living in the same house still needs a card of their own.

Two names, one bill.
