in December 1931. Career in the SS On 30 May 1931, Heydrich's discharge from the navy became legally binding, and either the following day or on 1 June he joined the Nazi Party in Hamburg. Six weeks later, on 14 July, he joined the SS. His party number was 544,916 and his SS number was 10,120. Those who joined the party after Hitler's seizure of power in January 1933 faced suspicions from the Alte Kämpfer (Old Fighters; the earliest party members) that they had joined for reasons of career advancement rather than a true commitment to Nazi ideology. Heydrich's date of enlistment in 1931 was early enough to quell suspicion that he had joined only to further his career, but was not early enough for him to be considered an Old Fighter. In 1931, Heinrich Himmler began setting up a counterintelligence division of the SS. Acting on the advice of his associate Karl von Eberstein, who was Lina's friend and Heydrich's godbrother, Himmler agreed to interview Heydrich, but cancelled their appointment at the last minute. Lina ignored this message, packed Heydrich's suitcase, and sent him to Munich. Eberstein met Heydrich at the railway station and took him to see Himmler.

At first he had to share an office and typewriter with a colleague, but by 1932 Heydrich was earning 290 Reichsmarks a month (), a salary he described as "comfortable". As his power and influence grew throughout the 1930s, his wealth grew commensurately; in 1935 he received a base salary of 8,400 Reichsmarks () and an allowance of 12,000 Reichsmarks () and by 1938 his income increased to 17,371 Reichsmarks (), annually. Heydrich later received a Totenkopfring from Himmler for his SS service. On 1 August 1931, Heydrich began his job as chief of the new 'Ic Service' (intelligence service). He set up office at the Brown House, the Nazi Party headquarters in Munich. By October he had created a network of spies and informers for intelligence-gathering purposes and to obtain information to be used as blackmail to
