Plaintiffs, James B. Biddle, Jo Ann Biddle, Vernon R. Shetler and Rickey Shetler, appeal from the entry of summary judgment in favor of defendant, The Mountain States Telephone and Telegraph Company (Mountain Bell), in this breach of contract action.

Summary judgment was granted on grounds that the action was barred by A.R.S. § 12-543, which provides a three year statute of limitations for debt evidenced by an oral contract. This action was filed three years and ten months after the cause of action arose.

Plaintiffs contend that A.R.S. § 12-548, which provides a six year statute of limitations for debts evidenced by a written contract, is applicable. It is conceded, however, that the written tariffs on file with the Arizona Corporations Commission form only a part of the contract for telephone services. The contract between the parties did not arise until oral requests for telephone services were made and Mountain Bell orally agreed to supply them.

It is axiomatic that a contract which is partly oral and partly written is an oral contract. Beane v. Tucson Medical Center, 13 Ariz.App. 436, 477 P.2d 555 (1970); Annot., 3 A.L.R.2d 809 §§ 5, 6 (1949). Therefore, the three-year statute of limitations applies in this case and the action is barred.

AFFIRMED.
