Panasonic: Secret Codes and Tricks for All Vintage Models — Complete Guide 2026

This is the definitive guide to Panasonic secret codes for vintage phones. The Japanese brand Panasonic — which produced GSM phones for Europe between 1999 and 2004 before withdrawing from the market — has a unique code system based on numeric sequences followed by double OK presses, and the very rare *369# code for accessing the lock/unlock menu. This guide covers all main GD, VS, X and G series models with verified codes and complete network unlock procedures.

How the Panasonic Code System Works — Read First

Panasonic uses three different approaches depending on the model family:

  1. GD67/GD68/GD87/GD88/X70/P341i — unlock via 746 + 2×OK without SIM
  2. GD50/GD55 — direct unlock with **00012*CODE# without SIM
  3. X60/X400 — unlock via 52824** with accepted SIM
  4. G60 — with non-accepted SIM inserted + 2×OK

Universal Panasonic master reset: *01763*737381# — works on A100, A101, A102, G50, G51, G70, GD55. Full reset of user data and user code.

Software version: *#9999# — type it 5 seconds after switching on — works on GD75, GD67, GD87. This precise timing is rarely documented correctly anywhere.

The *369# Menu — The Rarest Code of All Vintage Panasonic Phones

Works on GD55, GD67, GD75, GD87 and similar models.

How to access:

  1. From the main screen type *369#

Panasonic Network Unlock — Complete Procedures by Family

GD67, GD68, GD87, GD87e, GD88, X70, P341i — 746 procedure

  1. Switch the phone off
  2. Remove the SIM card
  3. Switch the phone on without SIM
  4. Type 746 from the main screen
  5. Press OK twice
  6. A new menu appears — select "NCK"
  7. Enter the NCK unlock code you received
  8. Phone is now unlocked

Note: if the menu doesn't appear after 746 + 2×OK, try the alternative: 52824** → 746 → OK×2 → select NCK.

GD50 and GD55 — **00012* procedure

  1. Switch on without SIM card
  2. Type: **00012*CODE# (where CODE is the specific NCK code for your IMEI)
  3. The phone unlocks directly

This procedure is unique to these two models — it does not work on other Panasonic phones.

X60 and X400 — 52824** procedure

  1. Switch on with the accepted SIM (the original operator SIM)
  2. Type 52824**
  3. Unlock menu appears — select "NCK"
  4. Enter the NCK code
  5. Phone is unlocked

Alternative X60/X400 procedure:

  1. Switch on with accepted SIM
  2. Type 52824**
  3. Then type 746 and press OK twice
  4. Select NCK → enter code

G60 — non-accepted SIM procedure

  1. Insert SIM from a different operator
  2. Switch on → enter SIM PIN and confirm
  3. Press OK a second time
  4. Phone asks for unlock code
  5. Enter the NCK code

Panasonic GD55 — Full Secret Codes

The Panasonic GD55 (2001) was one of the most innovative phones of its time — the first European Panasonic with TFT colour display (256 colours), integrated 0.3MP camera and MMS support. Compact and rugged, typically Japanese design.

IMEI: *#06#

Master reset: *01763*737381# Performs a full reset of user data and phone code. Also works on GD50, G50, G51, G70.

Software version: *#9999# (5 seconds after switching on)

Network unlock GD55: **00012*CODE# procedure without SIM (see above)

Hidden menu: *369# then * → navigate with 7, 4, 6, Menu, Menu

EFR (Enhanced Full Rate): *3370# (enable) / #3370# (disable)

Half Rate: *4720# (enable) / #4720# (disable)

Collector note GD55: The camera was integrated into the upper flip — an elegant mechanical solution that very few other phones had. The *01763*737381# software is identical to what Panasonic technicians used in the factory for the final reset before packaging.

Panasonic GD67 — Full Secret Codes

The Panasonic GD67 (2002) is the most iconic European Panasonic model — first with CSTN colour display at 4096 colours, 40-voice polyphony and optional external camera.

IMEI: *#06#

Software version: *#9999# (5 seconds after switching on) Firmware version in format "GD67_EUR_V01_03_0001_P" — "EUR" indicates European version, the number after identifies the firmware revision.

Network unlock GD67: 746 + OK×2 without SIM (see above)

Hidden menu: *369# then * → 7, 4, 6, Menu, Menu → lock menu

EFR: *3370# / #3370#

Half Rate: *4720# / #4720#

Master reset: *01763*737381#

Firmware update trick: The GD67 was one of the few phones of its era with an official firmware update via data cable — the "Panasonic LOG Reader v5.0" software allowed reading and updating the firmware. Newer firmware versions fixed WAP browser and MMS handling bugs.

GD67 vs GD68: The GD68 is identical to the GD67 but with GPRS Class 10 instead of Class 8. The code *#9999# shows the firmware version that distinguishes them — versions labelled "GD68" support the higher GPRS class.

Frequently Asked Questions

Why must *#9999# be typed 5 seconds after switching on? Because the Panasonic GD/VS firmware has a boot time window in which the code is intercepted before the operating system finishes loading. If typed too late (after 10+ seconds) the phone is already in the main menu and the code isn't recognised. This is one of the rarest timing tricks in the entire vintage phone sector — almost no website documents it correctly.

What's the difference between the GD67 and GD55 unlock procedures? The GD67 uses 746 + 2×OK without SIM — enters a text-based unlock menu. The GD55 uses **00012*CODE# without SIM — directly enters the NCK code without any intermediate menu. These are two completely different firmware architectures despite the phones appearing similar.

Does the master reset *01763*737381# work on all Panasonic phones? It works on A100, A101, A102, G50, G51, G70, GD55 and models of the same era. It does not work on GD67, GD87, GD88 which use a different reset system accessible via the *369# menu.

Why did Panasonic exit the European market in 2004? Panasonic couldn't compete with Nokia, Motorola and Samsung in the entry-level segment, while the premium segment was dominated by Sony Ericsson and Nokia. The decision was made to focus on the Japanese W-CDMA market where Panasonic was the leader. The GD93 and GD95 were the last models distributed before the closure.

How do I get the NCK unlock code for my Panasonic? The NCK code is calculated from the phone's IMEI using the Panasonic algorithm. No universal code exists. Available from online unlocking services by providing the IMEI.
