Gare Du Nord Paris Automatic Locker Service (Consignes Automatiques)

Look for this sign to arrive at the luggage lockers

 We arrived in Paris early in themorning while the usual check-in timefor the hotel is at least from noontime. In fact, the Hotel we took has a check-in time that starts at 14:00 or 2:00 PM. We had however some luggage with us and at the same time, we did not want to waste 7 hours just by waiting for the chec-in. What we did was to look for a locker service in major train stations in Paris. We went to Gare du Nord just to be sure. Moving around the city was not a problem for us since we have Paris Visite Pass that enables us to move around the city without hassles and without additional fees.

Directly down this elevator, around 2 meters to the right are the lockers. 
As you see, it's near the car rental too, "Location  de Voitures".

At the Gare du Nord, the lockers "Consigne et Service" was not easy to be found. The label was not always present, we still had to look for it. It was at the further right wing of the building (to your left when you enter from the main entrance) if I remember good. Otherwise, just look forthe sign as this service surely exists at the Gare du Nord Paris.

The service cocts Eur 7,00 for a amaximum of 48 hours usage for small lockers and for bigger lockers, I don't remeber good whether it's Eur 9 something or Eur 11 for a 48 hours usage. We used the small locker for our stuff good for 5 days for 2 persons.

Tips
1. Be ready with cash because the machine does not return the change.
2. Remove all metallic items from your body before entering to avoid detectors (we were not admitted in until we were cleared)
3. We had to look for a place to change the money as we did not have cash, no possibility of changing cash inside, at least during the time we were there.
4. Lockers with "HORS SERVICE" indications are out of service, don't use it.
