How do you enter cheats in GTA IV?
Dial them on Niko's phone. Open the phone, enter the number and call; the effect applies immediately. The number then enters the contacts for later selection.

GTA IV handles cheats differently from the rest of the series: Niko takes out his phone and dials a number. Nothing triggers accidentally, and afterwards one click in the contact list is enough.

GTA IV handles cheats better than any game before or after it: they are dialled rather than typed. Niko takes out his phone, enters a number and the effect applies immediately.
This has two practical benefits. The dialled number enters the contact list, so one click is enough next time. More importantly, a cheat cannot start accidentally because the phone must be opened first.
The numbers resemble American telephone numbers and can be read as keypad words: GUN-555-0100 means weapons, COP-555-0100 police and DOC-555-0100 doctor. Remember those three letters and no list is needed.
GTA IV handles this unusually fairly. Cheats **do not prevent 100% completion**, contrary to claims about other games.
Most cheats disable achievement unlocking, but only for the saved game in which they are used. Quit and load an older cheat-free save, and unlocking works again.
Some achievements have their own conditions, however, and certain cheats block them permanently, especially those based on wanted levels and escaping police.
The safe method is the usual one: use cheats in a separate saved game and do not overwrite the clean playthrough.
Safe
| Number | Effect | What to watch for |
|---|---|---|
482-555-0100GTA-555-0100 | Restores health, armour and ammunition, and repairs the vehicle you are using. | The most useful number in the game. Vehicle repair particularly helps in missions where the car matters. |
362-555-0100DOC-555-0100 | Restores health and armour and repairs the vehicle. Ammunition is unchanged. | The better choice for a clean playthrough because ammunition management remains relevant. |
486-555-0100GUN-555-0100 | Advanced weapon set: baseball bat, combat pistol, combat shotgun, SMG, carbine rifle, sniper rifle and rocket launcher. | — |
486-555-0150GUN-555-0150 | Basic set: knife, pistol, shotgun, Micro Uzi, assault rifle, sniper rifle, Molotov cocktails and rocket launcher. | Paradoxically more useful when you do not want excessive firepower to undermine the playthrough. |
267-555-0100COP-555-0100 | Removes the wanted level. | During an escape-based mission, this can disrupt the script. It also permanently blocks some achievements. |
267-555-0150COP-555-0150 | Adds one wanted star. | Useful for seeing higher-level police responses without waiting. |
468-555-0100HOT-555-0100 | Changes the weather, cycling through eight states. | Repeated calls cycle to the desired state. Rain noticeably changes vehicle handling in Liberty City. |

No. Cheats do not prevent 100% completion. They disable achievement unlocking for the saved game in which they are used; restart and load an older cheat-free save to restore it.
Those based on wanted levels and escaping police. The wanted-level removal cheat blocks them irreversibly, so do not enter police codes during a playthrough intended for those achievements.

The Lost and Damned and The Ballad of Gay Tony have their own telephone numbers and vehicles. This list covers the main game.
Euphoria physics is the most interesting part of this game, and cheats remove much of its effect.
