Editing Secret code

=== In {{DnM+|nolink}} ===

In {{DnM+}}, codes consist of 22 {{Wp|hiragana}} characters in two rows of 11. They must be written in letters formatted in three lines, with the first line being {{nowrap|あいことば}} (''aikotoba'', meaning "secret password"), followed by two lines of the code. The letters can be sent to any villager, and will always result in a letter from the character on the card. The received letter itself is determined by the character, usually containing a certain variable string that is determined by the code itself. These letters arrive after two days of gameplay, and only three can be in transit at a time or they will be overwritten.

=== In {{PG|nolink}} ===

In {{PG}}, codes consist of 28 characters displayed as two rows of 14 characters each. I Valid code characters include all uppercase and lowercase letters of the English alphabet, the numbers 0, 2, 3, 4, 5, 6, 7, 8, 9, the ampersand (&), the at sign (@), the pound (#), and the percent sign (%). The number <code>0</code> and capital <code>O</code> are interchangeable, as are the number <code>1</code> and capital <code>I</code>; however, <code>1</code> is never generated in a secret code. When generated by [[Tom Nook]], a capital <code>I</code> can be distinguished from a lowercase <code>l</code> by the serif drawn at both the top and bottom of its stem. Codes are always preceded by special key symbol ({{Key}}), which must be the first line in a letter but is automatically provided when speaking to Tom Nook.

 

Passwords can either be input by sending them in a letter to a villager, or being told directly to [[Tom Nook]]. This may depend on the type of code, see [[#Types of codes]] below. The player will receive their item in a letter from a different character depending on the type of password two days later. While these are unlimited, Tom Nook will only distribute three items via password per game load. To redeem more items, the player must save and quit and then reload the game.

 

In {{DnMe+}}, codes consist of 32 hiragana characters again displayed as two rows of 16, and are preceded by あいことば like in {{DnM+|nolink}}. Like in {{PG|nolink}}, they can still be redeemed via mail or Tom Nook depending on the code type. Mailing a valid 22-character code from {{DnM+|nolink}} will instead result in one of three items exclusively obtained this way, the {{I|shop sign|DnMe+}}, {{I|decorative plate|DnMe+}}, or {{I|Tom Nook's autograph card|DnMe+}}.

{{code|Card E}}/"e-Reader card codes": These codes are by far the most common type of code, due to working for any town and player. They are primarily seen written on the back of most {{DnM+|nolink}} and {{PG|nolink}} [[e-Reader card]]s; they can also be seen by getting a certain score in minigames on the [[e-Reader]]. In {{DnM+|nolink}}, each character card will also show one of two codes when scanned on the [[Game Boy Advance|GBA]]; these were replaced with messages from the character on the {{PG|nolink}} cards. Additionally, [https://www.nintendo.co.jp/ngc/gafj/fami_pre/nbench.html Nintendo's online code] for the {{I|Nintendo Bench|PG}} in {{DnM+|nolink}} is this type of code. The way these codes work differs in each version:

*In {{PG}}, Card E codes are guaranteed a present, a particular item different from the one received when scanning the card at the [[eTM]]. If the letter is sent to the character on the card, there is either a 20%, 40%, 60%, or 80% chance of a common [[NES game]]{{Note|Possible NES games include {{I|Balloon Fight|Animal Crossing}}, {{I|Clu Clu Land|Animal Crossing}}, {{I|DK Jr MATH|Animal Crossing}}, {{I|Donkey Kong|Animal Crossing}}, {{I|Excitebike|Animal Crossing}}, {{I|Golf|Animal Crossing}}, {{I|Pinball|Animal Crossing}}, and {{I|Tennis|Animal Crossing}}.}} and an inverted chance of the particular item. If the letter is sent to any other villager, the particular item is guaranteed. They can ''only'' be sent by mail.

{{Code|Monument}}: Codes for {{DnMe+|nolink}} generated based on player and town names on Nintendo's now-defunct [[Object Delivery Service]] website, which, when given to Nook, allow for certain [[Object]]s in the player's town. The price for the object is embedded in the password as a 6-character string. This limits the price of objects to between 0 and 999,999 Bells. The password also contains the acre which the object is attempting to be placed in. If the specified acre has no signboards, Tom Nook will tell the player it is impossible to build the object there, and to generate a new password.

== List of official codes ==

Some contest codes were used by Nintendo to distribute items. The 12 [[Mario Theme]] items and the {{I|Nintendo bench|PG}} can only be obtained through these official codes. Codes for the Mario Theme were published in various issues of ''[[Nintendo Power]]'' magazine and on the game's official website.<ref>{{Cite web|url=https://web.archive.org/web/20030812032645/http://www.animal-crossing.com:80/special/delivery.jsp|title=Animal Crossing: Special Delivery|site=animal-crossing.com|archive-date=August 12, 2003|retrieved=October 22, 2020}}</ref> The {{I|Mario trophy|PG}} and {{I|Luigi trophy|PG}}, which can be obtained from [[raffle]]s and [[Crazy Redd's]], respectively, also had codes published in ''Nintendo Power''. The Nintendo bench code was published in issue 100 of ''{{Wp|Tips & Tricks (magazine)|Tips & Tricks}}'' magazine.

'''Contest loser:''' This message is received after 'losing' a contest code. Note that if the player attempts to reenter the code they may eventually 'win' the item.

'''e-Card minigame winner:''' This message was intended to be used by e-Card minigames when a player won. It is unused, as minigame passwords can only be mailed to villagers.
