What are the most common promo code patterns?

The most common patterns include WELCOME-based offers, SAVE-based offers, and 10%-off discounts.

Why should I sign up for store newsletters?

Signing up for store newsletters often provides immediate access to WELCOME-style promo codes.

What should I do if a promo code doesn't work?

Try variations of the code by swapping numbers, such as using SAVE15 if SAVE10 doesn't work.

Are promo codes guaranteed to work?

No, promo codes are not guaranteed to work as they can be retailer-specific, region-specific, time-limited, or tied to customer accounts.

We Analysed 55,637 Real Coupon Codes — Here Are the 20 You Should Actually Try First

There's a small ritual almost every online shopper knows: you reach the checkout page, spot the little 'Promo code' box, and pause.

Maybe you open a new tab to hunt around. Maybe you just type in a guess and hope for the best.

To find out whether those guesses ever work, HotDeals is a verified coupon platform where real users test promo codes so shoppers don't have to. The data team analysed 55,637 real, verified coupon codes collected across thousands of online stores.

The takeaway? Coupon codes are far less random than they seem.

A surprisingly small set of naming patterns accounts for a meaningful share of working discount codes online. So if you're staring at an empty promo box with nothing to lose, these are statistically the codes most likely to do something.

What the Data Shows

After analysing all 55,637 codes, three major patterns stood out.

1. 'WELCOME' Dominates Everything

Codes built around WELCOME — especially those aimed at first-time shoppers — were by far the most common pattern in the dataset.

Most common examples:

WELCOME10
WELCOME15
WELCOME20
WELCOME5
WELCOME
WELCOMEBACK

Among them, WELCOME10 appeared 1,732 times, accounting for 3.11% of every code analysed— more than twice as common as nearly any other individual code.

Taken together, the entire 'WELCOME' family sits in a category of its own.

2. 'SAVE' Codes Are the Universal Backup

The second major pattern centered around SAVE:

SAVE10
SAVE15
SAVE20
SAVE5

These are simple, generic, brand-agnostic codes used by retailers of every size.

If a store runs standard percentage discounts, there's a good chance some variation of SAVE exists behind the scenes.

3. The Number '10' Appears Everywhere

One pattern showed up across almost every naming style:

10% off is the default internet discount.

Whether attached to:

WELCOME10
SAVE10
10OFF
THANKYOU10
NEW10
EXTRA10
FIRST10
CART10
TAKE10
GET10

...the number 10 consistently appeared more than any other discount value.

If you only try one number, statistically, 10 is the best first guess.

The 20 Codes to Try First

Ranked by how often each one appeared across all 55,637 codes:

Rank	Code	Times Seen	Share of All Codes
1	WELCOME10	1,732	3.11%
2	WELCOME15	640	1.15%
3	SAVE10	630	1.13%
4	WELCOME	487	0.88%
5	10OFF	298	0.54%
6	WELCOME20	287	0.52%
7	SAVE15	253	0.45%
8	SAVE20	243	0.44%
9	WELCOME5	228	0.41%
10	THANKYOU10	224	0.40%
11	NEW10	209	0.38%
12	15OFF	180	0.32%
13	SAVE5	161	0.29%
14	HONEY10	160	0.29%
15	EXTRA10	132	0.24%
16	THANKYOU	125	0.22%
17	FIRST10	122	0.22%
18	CART10	120	0.22%
19	TAKE10	119	0.21%
20	WELCOMEBACK	110	0.20%

(GET10 lands just outside the top 20 at 104 appearances — worth a shot too.)

How to Actually Use These Codes

Start With Email Signup Offers

Many WELCOME-style codes activate immediately after signing up for a store newsletter.

In practice, spending 30 seconds entering an email address often works better than random guessing.

Match the Code to the Shopping Situation

Different naming styles tend to match different customer moments.

New customer?

Try:

WELCOME10
NEW10
FIRST10

Returning after a long break?

Try:

WELCOMEBACK

About to abandon your cart?

Try:

CART10

Retailers often structure promotions around these exact behaviors.

Swap the Number, Keep the Pattern

If:

SAVE10 doesn't work

...it's logical to try:

SAVE15
SAVE20

The same pattern applies to WELCOME codes as well.

Retailers frequently reuse the same naming structure across multiple discount tiers.

Don't Spend Forever Testing Codes

These patterns improve your odds — they do not guarantee success.

Trying two or three likely options makes sense.

Trying ten probably doesn't.

Important Caveats

A code being common does not mean it works universally.

Many promo codes are:

retailer-specific
region-specific
time-limited
tied to customer accounts or email lists

What this analysis provides is not a guaranteed shortcut — it's a statistically informed starting point.

The exact frequencies above represent a snapshot of the dataset at the time of analysis. Individual codes change constantly, but the broader trends — especially the dominance of welcome offers and 10%-off discounts — have remained remarkably stable over time.

Final Takeaway

Most promo code guessing feels random.

The data suggests it isn't.

A relatively small group of code patterns appears repeatedly across thousands of stores, especially:

WELCOME-based offers
SAVE-based offers
10%-off discounts

So the next time you hit a checkout page with an empty promo box, you'll at least have a ranked, evidence-based shortlist instead of a complete shot in the dark.
