Italy are hoping to build on a quarter-final finish at the 2019 World Cup, which was their first time in the tournament since 1999.
But they finished bottom of their group at Euro 2022 in England with only one point.
"This World Cup is important - just as the previous one - because it does continue the growth process. We have qualified for two World Cups in a row and this is extraordinarily important for the growth in Italy," said manager Melina Bertolini.
"Our movement keeps growing. It's a very young movement; it's still fragile."

Third-ranked Sweden are up against an Italy side that are 13 places below them at 16th.
Sweden midfielder Kosovare Asllani plays her club football in Italy at AC Milan and knows what to expect against Milena Bertolini's side.
"I'm quite used to that type of football. It's very focused on man-marking and we know that there will be tough situations," she said.
Sweden to out-smart Italy?

What's this? Sweden's players outsmarting the fashion conscious Italians - at least off the pitch - at the World Cup?
The question is: will they be smart enough to sink Le Azzurre on the pitch?
The winners of this game will join Spain and Japan in the last 16.

It's Saturday night in New Zealand's capital city and the bars and restaurants are rammed with revellers having a good time.
Many entertainment venues in Wellington are showing Women's World Cup matches on big screens and it was standing room only last night when England defeated Denmark.
This match hasn't quite got the numbers or the vibe from Thursday when defending world champions the United States drew 1-1 with the Netherlands here in front of a 27,000-plus crowd.
Still there is good support for both nations with plenty of yellow and blue for Sweden while Italy's unmistakable green, white and red flag is proudly on display around the stadium.

Team news - Sweden unchanged; Italy goalscorer Girelli again on bench
Sweden v Italy (08:30 BST)

Unsurprisingly, Sweden are unchanged from the team that started the game against South Africa when they came from behind to win 2-1.
Captain Kosovare Asllani plays her club football in Italy for AC Milan.
The vastly-experienced Caroline Seger, who is playing at her fifth World Cup, is not starting for the second straight game.
Italy once again include 16-year-old midfielder Giulia Dragoni from the start. Juventus forward Cristiana Girelli came off the bench to score the winner against Argentina in the last group game. But that is not enough to earn her a place in Milena Bertolini's starting XI.
There is one change as forward Sofia Cantore comes in for Valentina Giacinti.
