The Complete Guide to Bypassing AVS in Physical Goods Carding (2026)

[Investor]

A comprehensive, practical breakdown of Address Verification System mechanics, merchant configuration vulnerabilities, and step-by-step evasion techniques used in 2026.

What AVS Actually Is and Why It's Your Main Barrier​

Address Verification System (AVS) compares the billing address a customer enters at checkout against the address stored by the card-issuing bank. It's not a balance check, an identity check, or a fraud investigation — it's purely a data comparison between two address strings.

When you submit a card in an online store, the payment system sends two elements to the bank: the street number and the ZIP code. The bank returns one of dozens of codes:

AVS Code	Meaning	Merchant Response
Y	Full match (street + 5-digit ZIP)	Transaction approved
X	Full match (street + 9-digit ZIP)	Transaction approved
A	Address matches, ZIP does not	Soft decline — may pass
Z/P	ZIP matches, address does not	Soft decline — often passes
N	Neither matches	Hard decline — transaction blocked
U	AVS not supported by issuer	Depends on merchant settings
G	International address, not verified	Depends on merchant settings
S	AVS service not supported	Depends on merchant settings

Critical difference: Merchants configure their gateways differently. Some block any mismatch; others permit partial matches; some operate in "Bypass" mode (they check but don't block). Your goal is finding merchants with relaxed settings and exploiting known AVS vulnerabilities.

Method 1: Exact Billing Match (The Baseline)​

If you have complete cardholder data (Fullz), matching exactly is your safest option.

Step-by-Step:

1. Check the cardholder's address via Whitepages, TruePeopleSearch, or other verification services
2. Format precisely — "Road" vs. "Rd" can cause mismatches if the bank stores a specific format
3. Use the correct ZIP code — 5-digit ZIP is standard; sometimes banks store 9-digit ZIP+4
4. Enter by hand through your anti-detect browser — copy-pasting looks like automation

When this works: Quality Fullz data on a merchant with strict AVS. Success rate: 95%+.

Method 2: Address Line 2 Exploit (The Classic)​

This long-standing technique still works on automated AVS systems.

How it works: AVS checks only the first address line. Address Line 2 is not part of the verification process.

Step-by-Step:

1. Address Line 1 — enter the cardholder's exact address (e.g., "123 Main St")
2. Address Line 2 — enter the drop address (e.g., "Apt 4B, 456 Drop Ave")
3. AVS checks Line 1, finds a match, approves
4. Package ships to the Line 2 address

Practical Example:

Address Line 1: 123 Main Street (cardholder address for AVS)
Address Line 2: Apt 4B, 456 Drop Avenue (drop address for delivery)

Important: This works on automated gateways. On sites with human review, a full drop address in Line 2 may raise suspicion.

When this works: Many automated systems ignore Line 2 entirely. Some processors set combined length limits for both lines — exceeding can cause truncation. Visa Platform Connect truncates at 40 characters before sending to the bank.

Method 3: Numeric-Only Mismatch​

AVS compares only the numeric portion of addresses. It disregards street names entirely.

Step-by-Step:

1. Billing address — use the cardholder's full correct address
2. Shipping address — use the same house number, but an invented street name
3. Address Line 2 — enter the real drop address

Example:

Billing: 123 Main Street
Shipping: 123 Asdfjkl Street (same number, nonsense street)
Address Line 2: 456 Real Drop Avenue

Why this works: AVS checks only "123" against the bank's records. If the numeric portion matches, the transaction proceeds. Street names are ignored.

When this works: Gateways with primary reliance on numeric matching — which is the majority. This is a confirmed vulnerability in most AVS implementations. A user noted: "AVS only checks the numerical street address, zip code, and CCV numbers. It does not check your name. It does not check your street name".

Method 4: International Card Exploit​

Many non-US banks don't support AVS in the US format.

How it works: AVS is US-centric. When the merchant requests AVS, a non-US bank returns code "U" (unavailable), "G" (international unavailable), or "S" (service not supported).

Critical point: US terminals often prompt for ZIP code with international cards. Some accept UK postcode digits ; others require workarounds — SW1A 1AA becomes "11" then "11000". Outcomes vary.

Caution: Some merchants specifically decline transactions with code G/S on international cards. PayPal documentation notes: "The transaction is declined" for some international codes.

When this works: Merchants with "Relaxed AVS" or "Bypass" settings, and those accepting partial matches. Also works when using international payment processors that don't enforce AVS consistently.

Method 5: "Bypass" Mode Exploit​

Some merchants enable AVS but don't automatically decline mismatches.

How it works: PayJunction offers three modes:

Mode	Behavior
Match Address And ZIP	Hard decline on mismatch
Match Address Or ZIP	Needs at least one match
Bypass	Verifies but doesn't reject — you must manually review codes

In "Bypass" mode, an N mismatch is logged but the order still processes. Your job: find merchants using Bypass.

Step-by-Step:

1. Find Bypass merchants — typically small-to-medium stores
2. Enter billing = shipping — use cardholder address for both
3. After the order ships, reroute — use USPS Parcel Intercept when you get tracking
4. No AVS mismatch occurred because billing and shipping matched

Merchant AVS Configuration Types​

Ignoring AVS entirely: Merchant configures gateway to disregard AVS results. Process normally regardless. High fraud risk.

Relaxed AVS: Merchant makes certain fields optional. For example, Address Line 2 optional. May ignore postal code. Strips non-critical elements.

Strict AVS: Gateway rejects unless specific codes are returned. Matches by address, ZIP, or both.

Account-level settings: PayJunction allows per-terminal AVS settings.

Configuration	Behavior
Ignore AVS	No AVS check performed, full bypass
Relaxed AVS	Some fields optional; adjustments reduce declines
Match Address	Street match required, ZIP irrelevant
Match ZIP	ZIP match required, street irrelevant
Match Both	Both must match or transaction fails
Bypass Mode	AVS runs but doesn't decline — used for manual review

Full AVS Bypass Checklist​

markdown:

[ ] Determine card's BIN — identify bank region and AVS support
[ ] If Fullz is available: use exact billing match (Method 1)
[ ] If ZIP unknown: use Address Line 2 exploit (Method 2)
[ ] If targeting automated systems: test numeric-only mismatch (Method 3)
[ ] If using international card: use codes G/U/S to bypass (Method 4)
[ ] Look for merchants with "Bypass" or "Relaxed" AVS settings (Method 5)
[ ] Test on small amounts ($1-5) before scaling up
[ ] Log working combinations (merchant + BIN + method)
[ ] If human review is a risk: avoid exaggerated Address Line 2 entries

Beginner Mistakes​

Mistake	Why It Fails	How to Fix
Not checking BIN	You don't know if the bank supports AVS	Always check BIN before use
Using random addresses	Guaranteed AVS failure	Use cardholder's address or use bypass methods
Not testing small	You'll lose a card on a large order	Test $1-5 before scaling
Ignoring Line 2	Misses a simple bypass	Always use Address Line 2 for drops
Using same approach everywhere	Different merchants have different settings	Test and adapt per merchant
Assuming international bypass always works	G/U/S handling varies by merchant	If the merchant declines international, switch targets

Conclusion​

Bro, AVS is not an impassable barrier. It's a data comparison system with exploitable weaknesses:

1. Exact billing match — most reliable, requires good Fullz data
2. Address Line 2 — classic bypass, still works on automated systems
3. Numeric-only verification — only numbers matter, street names are ignored
4. International card exploit — works if the merchant accepts G/U/S codes
5. "Bypass" mode — target merchants who check but don't block
6. Merchant configuration — "Ignore AVS" and "Relaxed AVS" are your goals
7. Test every combination — each merchant and each card behaves differently

The Golden Rule: Don't try one method for all cases. Combine approaches, test on small amounts, log successful combinations, and adapt per target.

Good luck, brother. If you need anything, write.
