PIN

A PIN (Personal Identification Number) is the five-digit password used by agents to identify themselves to the Operator when capturing a payphone in Payphone Tag. It is the core credential that links a player to their account and all their captured payphones.

Generation

A PIN is generated automatically when a new agent registers at payphonetag.com. The registration system assigns both a PIN and an emoji callsign. These are stored in the player's browser session. Because there is no linked email address or other recovery mechanism by default, agents are strongly encouraged to record their PIN immediately, for instance by taking a screenshot or writing it down. A lost PIN means lost access to the agent account and all associated captures and points.

How it is used

When an agent calls the Payphone Tag number (07 5623 8255, also remembered as 07 LOAD TALK) from a Telstra public payphone, the Operator prompts them to enter their PIN using the keypad. The PIN is transmitted as DTMF tones. The Operator decodes these tones, verifies the PIN against the agent database, registers the capture, and announces the agent's current rank before ending the call.

Entering a PIN without a working keypad

If the payphone's keypad is damaged or non-functional, a PIN can still be entered by playing DTMF tones through the handset's receiver using a tone generator app on a mobile phone. Care is needed with volume: too loud and the tones distort and fail to decode; too quiet and the payphone microphone may not pick them up. Alternatively, a Phonecard programmed with the game number can be used to initiate the call without keypad input, after which the PIN can be supplied via DTMF tones.

Mnemonics

Because phone keypads associate letters with digits, agents can devise letter-based mnemonics for their PINs. Eight of the ten digits on a standard keypad correspond to groups of letters:

Digit	Letters	Digit	Letters
2	ABC	7	PQRS
3	DEF	8	TUV
4	GHI	9	WXYZ
5	JKL	0	(none)
6	MNO	1	(none)

For example, the Party line PIN 72789 spells PARTY. An agent with PIN 46537 might remember it as HOLES. This mnemonic system is the same one used for sending SMS messages from a payphone keypad, where pressing a digit repeatedly cycles through the associated letters.

Security

An agent's PIN is personal and must not be shared with others. Anyone in possession of a PIN can use it at any Telstra payphone to make captures under that agent's account, or to interfere with their territory. Players wishing to cooperate should form a Cell rather than share PINs.

Special PINs

The Party line PIN 72789 (PARTY) is a publicly known PIN that drops callers into an open conference call rather than registering a capture. It does not award points and is intended purely as a social feature.
