Your two Diet-Cokes-a-day habit now has a greater purpose, beyond giving you the ability to banter at speeds that'd make the Gilmore Girls envious. In the wake of Hurricane Harvey, Coca-Cola has announced that it's letting people use their rewards codes to turn into donations for those affected by the storm.

The codes — those long strings of numbers found under the bottle cap and on multi-packs of the soda — can be entered at Coke.com/give and converted into donations to the American Red Cross. Each code entered only translates to 5 cents donated, but hey, every penny counts. (Also, it's worth noting that while the code is separated onto two lines, you should type it in as one string of characters, without spaces.)

The company has also pledged $1 million to the organization, so that it can provide food, shelter, and other essentials to the thousands of people who lost their homes in the disaster.

Hurricane Harvey has been deemed the strongest hurricane to hit the U.S. in the past 12 years, destroying as many as 40,000 homes and leaving 300,000 people without power. Thirty people have died, according to the New York Times. Early estimates say the disaster caused $40 billion worth of damage.

Coca-Cola isn't the only company stepping up to aid those affected by the hurricane. Anheuser-Busch immediately halted production at one Georgia brewery to make canned water — it plans on delivering 155,000 cans this week to flood-damaged areas. MillerCoors partnered with mason jar maker Ball Corp. to send 50,000 cans of drinking water to Red Cross shelters in Texas. The beer company's also announced it will match employee donations to the Red Cross up to $25,000.

PepsiCo has donated $1 million to the Red Cross as well, and told Fortune it will provide purified drinking water and other supplies to areas affected by the storm.

Additionally, Walmart has pledged $1 million in cash and product donations to organizations assisting people affected by the hurricane, and Amazon will match up to $1 million worth of donations to the Red Cross Hurricane Harvey Relief Fund.

Kellogg is also sending 30 million servings of its cereals, Pringles, Nutri-Grain bars, Cheez-Its, and Keebler crackers and cookies. Almost 100 trucks are hitting the road to deliver the snacks to food banks in Texas and Louisiana. This is on top of the 1 million servings of food and $100,000 donation to Feeding America the company made on Monday.
